Cell Signaling Technology, Inc. Announces Novel Discovery Platform for Isolation of High-affinity Antigen-specific Monoclonal Antibodies Directly from Human Serum

DANVERS, MA – December 5, 2012 – Cell Signaling Technology, Inc. (CST) of Danvers, MA is pleased to announce that NG-XMT™, CST’s patent-pending proteomics discovery platform can derive antigen-specific monoclonal antibodies from human serum. In the November edition of Nature Biotechnology (30, 1039–1043) the application of CST’s NG-XMT™ technology to the identification and cloning of high-affinity, antigenspecific human monoclonal antibodies directly from plasma of human donors is described. The CST-authored paper describes proof of principle studies in which sera from a human donor vaccinated against hepatitis B virus (HBV) and a donor naturally exposed to human cytomegalovirus (HCMV) were used to generate diverse, highaffinity anti-HBV antibodies and high-affinity HCMV-neutralizing antibodies.

“CST has now demonstrated that our proprietary and patent-pending technology can be successfully applied to isolate endogenous human monoclonal antibodies with potential therapeutic value. The technology is also useful for vaccine development and for understanding basic questions in immunology,” said Roberto D. Polakiewicz, Ph.D., CST Chief Scientific Officer. “Moreover, our NG-XMT™ proteomics-based technology is faster and more efficient than other traditional methods.”

CST has long been an industry leader in the development and manufacture of high performance antibodies for basic and clinical research. CST antibodies are known for their exceptional quality and rigorous validation for research applications. The development of NG-XMT™ and the resulting ability to isolate monoclonal antibodies directly from human plasma is a manifestation of the company’s ongoing commitment to developing novel technologies with diagnostic and therapeutic applications.

“The NG-XMT™ technology will benefit our pharma, biotech, and academic partners around the world,” said Fenel M. Eloi, CST Chief Operating Officer. “CST is exploring all avenues to bring this technology to market and to positively impact patients’ lives.”
