AnaSpec Introduces New SensoLyteTM MMP ELISA Kits

San Jose, CA October 16, 2008

Matrix metalloproteinases (MMPs) belong to a family of secreted or membrane-associated zinc endopeptidases involved in both normal and diseased tissue remodeling. They are capable of degrading all kinds of extracellular matrix (ECM) proteins, but also can process a number of bioactive molecules. MMPs are key players in normal and pathological processes, including embryogenesis, wound healing, inflammation, arthritis, and cancer.

MMPs share common structural and functional elements and are products of different genes. The three common domains include the pro-peptide, the catalytic domain and the haemopexin-like C-terminal domain linked to the catalytic domain by a flexible hinge region. MMPs are initially synthesized as inactive (latent) zymogens with a pro-peptide domain that must be removed before the enzyme is active.

AnaSpec is pleased to complement its MMP product line with a suite of SensoLyteTM MMP ELISA Kits. These kits are ideal for quantitative detection of MMP proteins (latent and active forms) in serum, plasma, cell culture supernates and urine. The SensoLyteTM ELISA Kits use a convenient, 96-well plate based format with colorimetric read-out.

AnaSpec?s widely used fluorescent SensoLyteTM MMP Activity Assays measure active MMPs in a convenient, 96-well plate-based method with highly sensitive fluorimetric read-out. A colorimetric read-out MMP Activity Assay kit is also available.

About AnaSpec

AnaSpec is a leading provider of integrated proteomics solutions to the world?s largest biotech, pharmaceutical, and academic research institutions.  With a vision for innovation through synergy, AnaSpec focuses on three core technologies: peptides, detection reagents, and combinatorial chemistry.

BNC Collaborators Author High-profile Paper in Nature Nanotechnology

London, UK – 17 October 2008: Research by scientists collaborating with specialist product development consultancy, Bio Nano Consulting (BNC), into the workings of vancomycin – one of the few antibiotics that can be used to combat increasingly resistant infections such as MRSA – has been published in Nature Nanotechnology (October 2008). The researchers, led by Dr Rachel McKendry and Professor Gabriel Aeppli at the London Centre for Nanotechnology, developed novel, ultra-sensitive nanomechanical probes capable of providing new insight into how antibiotics work, paving the way for the development of more effective new drugs.

Commenting on the new research, Bio Nano Consulting CEO, Dr David Sarphie said “BNC was set up specifically to help companies apply nanotechnology tools to address real-world biomedical problems such as antimicrobial resistance. Working with the BNC allows companies access scientists who have expertise in numerous ground-breaking nanotech-related research areas, and this paper in Nature Nanotechnology is a great example of the highest quality research that they are undertaking.”

During the study Dr McKendry, Joseph Ndieyira, Moyu Watari and coworkers used cantilever arrays – tiny levers no wider than a human hair – to examine the process which ordinarily takes place in the body when vancomycin binds itself to the surface of the bacteria. They coated the cantilever array with mucopeptides from bacterial cell walls and found that as the antibiotic attaches itself, it generates a surface stress on the bacteria which can be detected by a tiny bending of the levers. The team suggests that this stress contributes to the disruption of the cell walls and the breakdown of the bacteria.

The interdisciplinary team went on to compare how vancomycin interacts with both non-resistant and resistant strains of bacteria. The ‘superbugs’ are resistant to antibiotics because of a simple mutation which deletes a single hydrogen bond from the structure of their cell walls. This small change makes it approximately 1,000 times harder for the antibiotic to attach itself to the bug, leaving it much less able to disrupt the cells’ structure, and therefore therapeutically ineffective.

“There has been an alarming growth in antibiotic-resistant hospital ‘superbugs’ such as MRSA and vancomycin-resistant Enterococci (VRE),” said Dr McKendry. “This is a major global health problem and is driving the development of new technologies to investigate antibiotics and how they work.

“The cell wall of these bugs is weakened by the antibiotic, ultimately killing the bacteria,” she continued. “Our research on cantilever sensors suggests that the cell wall is disrupted by a combination of local antibiotic-mucopeptide binding and the spatial mechanical connectivity of these events. Investigating both these binding and mechanical influences on the cells’ structure could lead to the development of more powerful and effective antibiotics in future.”

Established in late 2007, BNC provides a seamless concept-to-market route for the bio-nanotechnology sector.

Biological Drugs Spurring an Evolution in Injectable Drug Delivery

(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 .
