San Diego, CA (PRWEB) October 31, 2013 -- BPS Bioscience, Inc. (“BPS”) announces the availability of recombinant proteins, assay kits and screening/profiling service for Programmed Cell Death Protein 1 (PD-1) and its ligands (PD-L), PD-L1 and PD-L2.

PD-1, also known as PDCD1 and CD279, is an immunomodulatory receptor present on the surface of activated T cells and other immune cells. PD-1 has two ligands, PD-L1 (B7-H1, CD274) and PD-L2 (B7-DC, CD273), which are upregulated in most human cancers. Binding of PD-L1 to PD-1 negatively regulates T cell signaling and inhibits cytotoxic T cell activity, allowing the cancer cells to escape immune detection.

A number of pharmaceutical companies are actively developing monoclonal antibodies targeting PD-1 and PD-L1. These antibodies are believed to boost the immune system for the treatment of non-small-cell lung cancer, melanoma, and bladder, renal, and triple-negative breast cancers. The PD-1/PD-L pathway is also a therapeutic target for chronic viral-infections including HIV and HCV. PD-1 expression is upregulated on virus-specific T cells, and blockade of this system is hoped to decrease viral load by increasing T cell function. Additionally, the PD-1/PD-L interaction regulates self-tolerance and immunologic homeostasis, making these proteins promising drug targets for many autoimmune disorders including multiple sclerosis, arthritis, lupus, and type I diabetes.

BPS now offers a number of new tools to promote PD-1/PD-L research and drug discovery:

● High purity recombinant extracellular domains of PD-1, PD-L1, and PD-L2 proteins: These proteins are also available biotinylated with AviTag™ technology for detection assays.
● Four unique assay kits: These convenient assay kits are designed to screen monoclonal antibody or small molecule antagonists of PD-1 binding to either of the PD-L ligands. The kits are optimized for high-throughput screening applications using chemiluminescence detection.
● Screening and profiling services for PD-1, PD-L1, and PD-L2: BPS’s customizable services can determine IC50 values or screen multiple compounds against a single protein for the identification and evaluation of lead drug candidates.

BPS is the first company to offer assay kits and services for screening inhibitors of the PD-1/PD-L pathway. BPS plans to continue assisting researchers identify and validate novel drug targets by offering additional PD-1-related products and services in the coming months.
