Microneedle Drug Delivery Systems Moving Toward Commercialization by Converging with Existing Delivery Technologies
Last Updated on Wednesday, 4 May 2011 06:12 Written by Editor Wednesday, 4 May 2011 06:12
Evolutionary Design Enhancements Creating a Viable Path to the Market According to Greystone Research Associates
(Amherst, NH) – For the past decade a small group of device development companies, often supported by academic partners and national government technology transfer programs, have been attempting to commercialize drug delivery products based on arrays of microneedles. By creating channels in the stratum corneum, these devices were expected to deliver therapeutic drugs across the skin and into the dermal layers. While several product efforts focused on achieving a local anesthetic effect, the majority pursued a pharmacokinetic model that involved migration of the API via interstitial fluid to the vasculature to achieve systemic delivery.
After years of prototyping unique array designs, a several development programs have migrated toward improving the performance of existing delivery methods. While novel microneedle designs still exist, the evolving landscape can now be grouped into three main strategic approaches: (1) arrays mounted on the end of syringes to effect an injection with minimal discomfort; (2) stand-alone drug-containing devices (coated microneedles or microneedle reservoir patch) designed to be applied or attached to the skin directly; (3) two-step delivery systems that employ an array to create microchannels through the skin followed by a drug-containing patch designed to deliver the drug through the newly-formed microchannels.
Microneedle technology is attaining commercial viability at a time when drug developers are faced with new challenges as they assess ways to administer a new class of compounds with significant therapeutic potential. The commercialization of microneedle drug delivery devices such as the sanofi-aventis Intanza influenza vaccine, which is based on the Becton Dickinson Soluvia syringe-mounted microneedle array device, is a milestone in the transition of microneedle drug delivery from development to market place. Microneedle technology promises to impact health care by allowing the precise injection of therapeutic agents to prescribed locations below the skin.
A new research study, Microneedle Drug Delivery: Technology, Devices, Players, Markets and Prospects analyzes existing and emerging microneedle delivery products, product candidates and development programs, profiles market participants, and assesses key demand and technology factors influencing the commercial market and shaping growth in this sector.

Sanford-Burnham robots speed up path to discovery
Last Updated on Saturday, 24 July 2010 04:26 Written by admin Thursday, 8 July 2010 10:40
The work force at Lake Nona’s Sanford- Burnham Institute includes 90 scientific staffers, 60 administrators and support personnel — and a team of three robots. The robots are part of a $15 million investment from the National Institutes of Health and occupy a large, glass-enclosed room on the bottom floor of Burnham’s Lake Nona campus.
Although they resemble the robotic arms used in automobile assembly lines, these robots have a far different task: filling test tubes faster than a human being. And that, scientists say, will speed up the process of scientific discovery.
“The robots are from the automobile industry,” said Greg Roth, director of medicinal chemistry at Burnham’s Conrad Prebys Center for Chemical Genomics. “We use them because of the accuracy and precision of their movements.”
The robotic arms can fill miniature test-tube “wells” so tiny that 1,536 of them fit on a plate the size of an index card. Using such small test tubes allows researchers to save money on chemicals and compounds.
After filling the wells, the robotic arms take a plate of the tubes and subject them to numerous tests such as varying temperatures and pressures. The robots are connected to a main computer that compiles the data from the millions of tests.
Pharmaceutical companies developed the ultra-high throughput screening technology in the mid-1990s, but universities and nonprofit research institutions such as Burnham did not have access to the robots until recently.
Funded by NIH, the Burnham center and eight others around the country form the institute’s Molecular Libraries Production Centers Network. This resource library and network assists scientists in research and allows results to be shared across the public and private sectors.
The reason for the federal government’s interest? As the results of the Human Genome Project began pouring in, scientists found themselves with so many avenues to explore that they needed faster research procedures.
“My scientists like to say they can do more than a robot, but they can only do it for a day,” said Michelle Palmer, director of screening for the Broad Institute at Harvard and Massachusetts Institute of Technology.
“The humans can do it faster and better, but they can’t sustain it. We need to sustain this over months of effort and get it done exactly the same way every time,” Palmer said.

A new approach to functional screening of siRNA knockdown
Last Updated on Wednesday, 26 November 2008 01:55 Written by Editor Wednesday, 26 November 2008 01:37
KINGSTON, England, Nov. 25, 2008-Guava Technologies, Inc. presented at the recent Molecular Targets & Cancer Therapeutics Symposium* information on their recent advancements that describe an experimental methodology and the new Guava® Simplicity Analysis Software which exploit the advantages of plate based flow technology. These technological improvements result in an overall process that can significantly expedite the drug discovery process by providing a means for extraction of key findings from the highly complex data sets encountered with functional screening of siRNA knockdown assays.
Solid tumors comprise genetically heterogeneous cell populations whose growth and survival depends on the complex interplay of distinct, yet overlapping, signaling networks. A major challenge in developing a course of therapy is determining which signaling nodes to target for a specific malignancy. Profiles from siRNA gene silencing are integral to mapping disease-specific signaling cascade(s) and provide insight to key targets for therapeutic intervention. Successful siRNA screening relies not solely upon optimizing transfection, but also cell analysis systems capable of high content screening (HCS) at the single cell level, within overall populations (sample well), and across multiple data sets.
The presentation describes how the Guava EasyCyteâ„¢ Plus System, with integrated Guava Simplicity Software, provides a revolutionary platform for secondary target validation and compound screening. Guava Technologies’ flow cytometers overcome the limitations of inference-based measurements of transfection efficiency and protein knockdown through direct quantitiative analysis of populations at the single cell level. The Simplicity Analysis Software’s intuitive architecture and ease of use facilitates the process of asking biological questions on multi-dimensional data sets through visualisation of user-defined parameters in the form of heat-maps. Most importantly, comparative results are displayed at the experiment level rather than on an individual well/sample basis.
Specifically, using the EasyCyte Plus System in tandem with Simplicity Analysis Software, 23 agents were identified that had growth restrictive properties although significant variation across cell lines was observed. Further targeted gene knockdown via siRNA confirmed the presence of both activators and inhibitors of Camptothecin-induced apoptosis as well as gene targets for growth arrest. Screens for apoptosis and cell cycle, as well as phospho-signaling intermediates, defined compounds with mechanisms of action similar to and different from Camptothecin. Cell-based assays for phenotype and function revealed a number of cooperative and antagonistic interactions between signaling intermediates, their respective cascades, and cytoactive agents.
Overall, the acquired multiplex data set is shown to provide a more detailed view on the behaviour of each of the test compounds with respect to apoptotic induction, cell cycle progression, and the signaling cascades that regulate these cellular responses to drug treatment. In total, this experimental methodology, when used in conjunction with Guava Technologies’ cell analysis platforms and Simplicity Analysis Software, significantly expedites the drug discovery process by providing a means for extraction of key biological findings from complex result sets.

Bibby Scientific’s latest personal thermal cycler takes more samples, but no more space
Last Updated on Thursday, 23 October 2008 01:20 Written by admin Thursday, 23 October 2008 01:08
Bibby Scientific announces an addition to the Techne range of personal thermal cyclers – the expanded capacity TC-3000X. With a highly successful half-century track record in the design and manufacture of temperature control equipment, Bibby Scientific’s world-leading Techne brand is synonymous with robust, reliable, reproducible DNA amplification.
The new TC-3000X has two interchangeable block options. The 6 x 8 format 48-well block can be used with 0.2 ml microtubes or, for greater ease of handling when higher throughput is required, Techne has introduced 24 and 48-well plates and 8-tube strips. Alternatively, the 30 x 0.5 ml block offers significantly greater capacity than the usual 12 or 20 tubes of this size. The defined pressure, heated lid of the TC-3000X is fully height-adjustable, giving researchers the widest possible choice of consumables.
Rob Skehens, Marketing Director, Bibby Scientific, puts the new Techne thermal cycler in context: ‘With the increased use of PCR techniques, demand for higher throughput has grown and the traditional 25-tube capacity of personal thermal cyclers is no longer sufficient for many users. The TC-3000X not only fits a 48-well block for 0.2 ml tubes within the same small footprint as our lower capacity TC-3000 model, it is also unique among personal thermal cyclers in accommodating as many as 30 x 0.5 ml tubes. With two block types which are easily interchangeable, plus an adjustable lid enabling a multitude of different consumables to be used, the TC-3000X offers unrivalled versatility – and at low cost.’
The TC-3000X has exceptional block uniformity of less than ±0.2 °C at 50 °C, as well as the fastest heating rate of all 48-well cyclers in the market at 3.3 °C per second.

New Benchtop LC-MS System
Last Updated on Wednesday, 9 July 2008 03:34 Written by Fred Wednesday, 9 July 2008 03:34
Thermo Fisher Scientific Inc. announced that it will launch the Thermo Scientific Exactive, a new benchtop LC-MS system designed for compound screening and identification applications, at ASMS 2008. Exactive leverages proven mass analyzer technology from the LTQ Orbitrap platform, the recognized standard for accurate mass and high resolution measurement, to provide precise and confident information. It is fast, easy-to-use and cost effective to operate, making it an ideal instrument for non-experts in routine analytical laboratories.”Orbitrap technology has been an important driver of LC-MS growth in the world of biology,” noted Ian Jardine, vice president of global research and development at Thermo Fisher Scientific. “We asked ourselves what we could do to fully realize the potential of this technology, to make it even more accessible to users with routine toxicology, environmental and drug development workflows. The result is an instrument that we consider a real breakthrough, that can be applied to a great number of challenging new applications.”
The Thermo Scientific Exactive LC-MS streamlines many of the technical steps that normally require specialized set up and operation. An intuitive software interface makes the system easy-to-use in both expert and “walk-up” mode, while ensuring precise mass identification of target compounds over a
wide concentration range.
While simple to operate, Exactive sets new standards for LC-MS performance, at resolutions of up to 100,000. When combined with excellent single scan mass accuracy in positive and negative modes, Exactive becomes an ideal system for common screening and high-throughput applications. “Mass accuracy plays a critical role in reducing analysis times and increasing confidence even in routine measurements,” notes Dr. Jardine. “Co-eluting compounds in complex matrices can be screened and confirmed in a single experiment simply by reanalyzing data at a higher resolution. For screening of isobaric compounds such as pesticides that differ by only a few milli-mass units, this accurate mass capability will be of enormous value.”

Biological Drugs Spurring an Evolution in Injectable Drug Delivery
Last Updated on Thursday, 3 January 2008 07:48 Written by admin Thursday, 3 January 2008 07:48
(Amherst, NH) – The success of recombinant protein drugs such as Enbrel, Remicade, and Herceptin in treating refractory conditions is fueling the search for protein and peptide-based therapeutic agents in oncology, inflammation and a host of other disease classes. Led by the proliferation of antibody-based drug candidates, biological drugs as a class continue to outpace all other NCEs in development pipelines and clinical trials. This shift away from small molecule drugs is creating opportunities for drug developers, device designers, packagers and – ultimately – pharmaceutical marketers.
Because biological drugs most often target chronic conditions, dosing strategies and treatment protocols must be developed for long-term use, often for self-administration by patients who may have limitations directly related to their condition. The powerful physiological effects of antibodies, hormones and other biological drugs also increase the need for safety and compliance.
Compliance with drug therapy and disease management protocols has been and is a primary concern within the healthcare and pharmaceutical industries. Efforts to enhance compliance are having a non-negligible effect on drug formulations and delivery decisions, and can be a significant factor in the prescribing decisions of most physicians. Compliance concerns have driven and continue to drive investment in new drug delivery technologies.
As patients live longer and are diagnosed with chronic and often debilitating ailments, the result will be a dramatic increase in self-administration of drug therapies in non-traditional settings for a number of conditions. This trend is creating an increased interest in routes of administration that are patient-friendly and cost-effective. Pharma company decision makers have come to the realization that new drug product success no longer only depends on the medication itself but also on achieving a patient-friendly form of application.
New injectable delivery device designs currently being developed will create new opportunities for alternative injection methods. Reusable injectors designed to accept prefilled syringes or drug cartridges will improve ease-of-use and increase alternative device share of the growing self-injection market. Partnerships between device suppliers and pharmaceutical companies will foster market acceptance of new injection devices for a host of new therapies such as therapeutic vaccines, DNA-based drugs, and protein-derived biologics.
These findings are contained in a comprehensive report, Injectable Drug Delivery: Evolving Markets, Emerging Opportunities. More information is available at www.greystoneassociates.org .

Burnham Institute Selects Labcyte Acoustic Liquid Handling Technology
Last Updated on Saturday, 1 December 2007 08:06 Written by admin Saturday, 1 December 2007 08:06
Sunnyvale, CA November 15, 2007 – Labcyte Inc. will supply Burnham Institute for Medical Research (Burnham) with more than $2.3 million worth of Echo® liquid handlers for use in screening large biological libraries. The systems will be installed at both the Institute’s LaJolla, (CA) and Lake Nona, Orlando (FL) campuses. These instruments will be part of the world’s largest screening system and will bolster Burnham’s research and drug discovery efforts, which include research on cancer, neurological diseases, aging, diabetes, and obesity.
Burnham is one of the nation’s 10 collaborating centers of excellence funded under a special initiative created by the National Institutes of Health, which together comprise the largest public-sector drug discovery effort in history. The state-of-the-art Labcyte technology will improve screening results while reducing operating costs for Burnham and the collaborating network advancing this historical effort. The systems will be delivered over the next six months.
“The Echo liquid handlers were selected because their unique acoustic technology will enhance our ability to miniaturize assays, reduce compound waste, and meet throughput requirements,” explained Dr. Stefan Vasile, Director of the Chemical Library Screening Facility for Burnham Institute. “The Echo systems will be used for compound plate-to-plate transfer, reformatting, dose-response experiments and hit picking.”
“Our patented acoustic droplet ejection technology dramatically reduces waste while cutting operating expenses,” said Dr. Elaine J. Heron, Labcyte CEO. “Traditional liquid handlers are prone to poor precision and accuracy as transfer volumes are decreased. Researchers who require flexibility in their processes and biology find that the Echo systems provide that for them easily, quickly, and cost-effectively.”

Brady labelling technology
Last Updated on Saturday, 1 December 2007 07:27 Written by admin Saturday, 1 December 2007 07:27
Brady’s proven labelling technology protects against the potential disaster of being unable to identify a sample due to the label falling off!
Laboratory labelling presents many challenges: labels may be subjected to hostile environments, solvents and other chemicals and extreme temperatures. They are also applied to widely varying surfaces and sample shapes and sizes. Sometimes, as in field sampling, labels have to be used in dirty or greasy situations. Under these conditions, the risk is that labels may become detached from the sample they are intended to identify. Of course, this problem may only become apparent when it’s too late!
Brady scientific labelling systems have been developed with these conditions in mind. For example, there are 10 different adhesives to choose from to suit virtually any application, with technical advice to make the right choice, and there are labels specially developed for the laboratory environment.
The Brady Freezerbondz™ range can be applied direct to new or frozen surfaces and survives exposure to common laboratory environments such as liquid nitrogen and temperatures from freezer (-196°C) to autoclave (up to 121°C). These labels also show excellent chemical resistance when exposed to solvents such as DMSO and Xylene.
Alternatively, Brady’s B461 self-laminating labels also provide exceptional permanence under extreme conditions. These labels combine a white label area with a clear overlaminating area that not only protects the legend but allows visibility of the sample itself and are available to suit all standard laboratory consumables – vials, tubes and slides.
The Brady Corporation has offices in 24 countries and is represented in over 100. Research laboratories in the US and Europe ensure a continuous programme of product innovation, evolution and improvement.

Device Offers Pharmaceutical Makers A Fast, Cheap and Safe Way to Screen Potential Drug Compounds
Last Updated on Tuesday, 20 November 2007 02:44 Written by Fred Tuesday, 20 November 2007 02:44
A new device invented by researchers at the University of Virginia could save pharmaceutical companies significant time and money in screening potential new drug compounds.
“We want to help the pharmaceutical industry identify effective therapuetic compounds by allowing them to fail early, fail fast, and fail cheap before going to very expensive animal studies,†said Brett Blackman, an assistant professor in biomedical engineering.
Blackman and Brian Wamhoff, assistant professor in the department of medicine (cardiovascular division), have teamed up to create the novel system, HemoShear 2.0, which offers researchers for the first time the ability to observe the behavior patterns of human vascular cells under a variety of blood flow conditions that occur inside the body’s cardiovascular system.
HemoShear 2.0 models the early indicators of atherosclerosis — hardening or narrowing of the arteries — by placing actual human vascular cells (i.e., endothelial and smooth muscle cells) in an environment that mimics an artery with blood flowing through it. Data from the exposure can be measured and recorded.
HemoShear 2.0 can help test the efficacy of therapeutic compounds and aid in early stage toxicity studies. Instead of testing drug compounds on isolated cells, which can produce false negatives, drug companies can use the device to test compounds in a more realistic environment.
“What the pharmaceutical industry lacks is the ability to mimic an organ ex vivo,†Wamhoff said. “We know that as soon as we take an organ and disperse the cells, those cells are no longer like they were in the body. If you apply a novel compound to that cell, the response you get might be real but it’s not meaningful in the context of the disease. When you go to animal studies, that response may not carry over in the blood vessel. It is clear that human-based biomimetic models are needed to fill this gapâ€
Atherosclerosis is considered the most important underlying cause of heart attack or stroke. The disease tends to occur at locations in the arteries where blood flow is compromised, causing detrimental changes in both the cells lining the interior of blood vessels (endothelial cells) and the cells found in the wall of blood vessels (smooth muscle cells).
Using an MRI, the researchers determined the rhythmic pattern at which blood flows through different arteries in human subjects. “We are then able to simulate the same flow patterns in those areas that are more or less susceptible to atherosclerosis and observe how the cells respond to these flow patterns in HemoShear,†Blackman said.
According to Wamhoff, this kind of modeling offers unique opportunities to observe the cells and their interaction. “Research has been conducted wherein human cells are isolated to observe behavior patterns, but there are no available models that allow one to accurately study the intricate communication between endothelial cells and smooth muscle cells in a setting that mimics actual blood flow in the body.â€
This communication is important, the researchers say, because the cells lining the interior of the blood vessels, the endothelial cells, recognize different blood flow patterns imposed upon them and respond by expressing or repressing genes. This, in turn, influences their interactions with the cells found in the walls of blood vessels, the smooth muscle cells — interactions that, the researchers found, may lead to the onset of early-inflammation-associated atherosclerosis in certain arteries.
Using HemoShear 2.0, the researchers have been able to recreate blood flow patterns in bifurcating and bulbous areas like the internal carotid that are more susceptible to the disease (atheroprone areas) and the pipe-like arteries like the common carotid that are less susceptible to the disease (atheroprotective areas).
Using a synthetic elastic layer that is similar to a real blood vessel wall, endothelial cells are plated on the top surface and smooth muscle cells on the bottom surface. Then, the different blood flow patterns modeled from human circulation are applied to the endothelial cells through rotation of a motor-driven cone system. The findings: the blood flow can influence both endothelial and smooth muscle cell behaviors.
When subjected to atheroprotective blood flow patterns, the endothelial cells aligned with the direction of the blood flow, and the smooth muscle cells aligned perpendicularly to the flow as is true in a healthy blood vessel. In stark contrast, the atheroprone type of flow caused the endothelial cells to move away from their parallel structure while smooth muscle cells moved away from their perpendicular structure. This remodeling mimics the early phases of the diseased state of the artery; the blood flow pattern associated with atheroprone areas resulted in inflammation in both cells reminiscent of early hallmarks of atherosclerosis. This was confirmed through evaluating gene and protein expression profiles in both cell types.
“The results of this study validate the use of this novel co-culture system as a relevant biomimetic vascular model for studying early atherosclerotic events,” said Tom Skalak, professor and chair of the U.Va. Department of Biomedical Engineering. “The cells’ responses to these carefully controlled models of blood flow can now be used to develop therapeutic interventions for detection and treatment of vascular diseases — it has the potential to be revolutionary.”
Blackman,Wamhoff, and Dr. Norbert Leitinger (department of pharmacology) have formed a collaborative entity — the Laboratory of Atherogenesis — to begin using the HemoShear system to make these translatable discoveries in atherosclerosis.
A provisional patent has been filed for HemoShear 2.0. The research that HemoShear 2.0 made possible was spearheaded by a biomedical engineering graduate student, Nicole Hastings (’08), and is published in the American Journal of Physiology — Cell Physiology.

New Forensic Toxicology Application from Applied Biosystems/MDS SCIEX Improves Accuracy of Screening for Drugs of Abuse
Last Updated on Tuesday, 23 October 2007 03:06 Written by Fred Tuesday, 23 October 2007 03:06
FOSTER CITY, Calif.–(BUSINESS WIRE)–Applied Biosystems (NYSE: ABI), an Applera Corporation business, and its joint venture partner, Sciex, a division of MDS Inc.’s Analytical Technologies business, (NYSE: MDZ, TSX: MDS), today introduced a new, automated toxicology testing application designed to better identify drugs of abuse, such as cocaine, heroin and date rape drugs for forensic investigations.
The new Cliquidâ„¢ Drug Screen and Quant Software for Routine Forensic Toxicology application equips toxicology laboratories for the first time with a built-in library of 1,200 compounds and a search reporting function designed to screen hundreds of drugs in less than 20 minutes. This software application is an advancement over existing toxicology testing methods. It enables faster delivery of results, more thorough screening and, ultimately, more accurate analysis to be used as evidence in criminal court cases.
Toxicology laboratories are relied upon for the testing of narcotics and other substances in a variety of cases such as impaired driving, homicides and sexual assaults. For example, if a person dies in a car accident, investigators turn to toxicology laboratories to ascertain whether or not the driver was impaired. In sexual assault cases, toxicology testing can help investigators determine if the victim was unknowingly drugged to facilitate the crime.
Identifying an expanding array of ‘street’ drugs has created new challenges for toxicologists, necessitating widespread re-evaluations of testing and analysis techniques to help prevent emerging derivatives of substances from slipping through the process undetected.
Scientists at the University of California, San Francisco (UCSF) are among the toxicology scientists at laboratories around the world who are increasingly expected to deliver accurate results in detecting a broader range of drugs of abuse. Toxicology laboratory personnel at UCSF have evaluated this new Cliquid software application.
“The accuracy of the test results is critical in toxicology analysis and interpretation,†said Dr. Alan Wu, chief of the chemistry and toxicology laboratories at San Francisco General Hospital, and professor of laboratory medicine at the University of California, San Francisco. “The new Cliquid software application for drug screening promises to make interpretation of toxicology results more efficient.â€
Cliquid Drug Screen and Quant Software for Routine Forensic Toxicology is the first dedicated application that utilizes liquid chromatography-mass spectrometry (LC/MS/MS), an advanced analytical technique for screening compounds. The high degree of sensitivity, minimum sample preparation and short run times of this technique result in being able to analyze more sample per unit time at a lower cost than other techniques, such as LC or gas chromatography-mass spectrometry (GC/MS). Traditional toxicology testing technology, which uses UV-based liquid chromatography, has been limited to detecting high concentrations of a narrow range of drugs because of the limited sensitivity of that technology.
The Cliquid software application reduces the complexity for routine testing to support greater confidence and throughput. The 1,200 compounds in the application’s built-in library consist of drugs of abuse, pharmaceuticals, poisons and metabolites to provide a complete analysis of what may have been ingested. The automatic LC/MS/MS-based library then simply searches for each of those substances through a simple, turnkey workflow.
“Results obtained from a toxicology laboratory can make or break an entire forensic investigation,†said Laura Lauman, president for Applied Biosystems’ proteomics and small molecules division. “Applied Biosystems/MDS SCIEX is responding to our customers’ requests for advanced tools that eliminate the complexity and limitations of traditional techniques and more quickly deliver irrefutable results.â€
The Applied Biosystems/MDS SCIEX Instruments joint venture has a 20-year history of innovation and a broad portfolio of mass spectrometry-based technologies and systems that enable advancements in research laboratories in biotechnology, biomedical and pharmaceutical fields. Applied Biosystems Global Services offers professional consulting services specifically designed to help toxicology laboratories maximize their investments in new systems and software.
“The innovative Cliquid software application has the potential to have a significant impact on the rapidly evolving field of toxicology,†said Andy Boorn, president for MDS Analytical Technologies. “The incredible precision of our mass spectrometry technology can help toxicologists meet the challenges they face today in their analysis for forensic cases.â€

Sigma-Aldrich Introduces N-TER Nanoparticle siRNA Transfection System for Delivery of siRNA Into Difficult-to-Transfect Cell Types
Last Updated on Thursday, 18 October 2007 01:03 Written by admin Thursday, 18 October 2007 01:03
ST. LOUIS, Oct. 18 /PRNewswire-FirstCall/ — Sigma-Aldrich announced today the global release of the N-TER(TM) Nanoparticle siRNA Transfection System. N-TER allows researchers to reproducibly interrogate gene function, via siRNA transfection, in model cell types that have previously not been considered amenable to conventional lipid-based siRNA delivery reagents.
“Traditional lipid-based siRNA transfection reagents exhibit a number of drawbacks, including high cell death rates and a limited ability to deliver siRNA into a variety of cell types, such as primary, neuronal, differentiated, and nondividing cells,” said Tim Fleming, Director of Global Commercial Marketing at Sigma-Aldrich. “Our goal is to introduce a reagent into the scientific community that effectively bypasses these historic limitations and enables siRNA transfection to be performed in a wider variety of model systems.”
The N-TER Nanoparticle siRNA Transfection System circumvents the limitations of lipid-based transfection reagents by relying on a stable nanoparticle, formed by the blending of siRNA and the N-TER peptide, to quickly enter into the cell’s cytoplasm to deliver its siRNA cargo.
In addition, due to the reagent’s stability, stocks of N-TER/siRNA Nanoparticles can be stored for long periods of time and used for subsequent transfections, increasing standardization and reproducibility in all transfection experiments targeting the same gene.
“Our research on the functions of West Nile Virus proteins involves looking at gene function in a number of different cell types,” said Dr. Tom C. Hobman, Professor of Cell Biology at the University of Alberta. “We tested a number of siRNA delivery reagents before using N-TER. Once we tried N-TER, we were very impressed with its ability to reproducibly deliver siRNA into our cell types of interest, with minimal cellular toxicity.”
