PBL Assay Science was founded in 1990 by Dr. Sidney Pestka and Joan Pestka as a family-owned business operating out of the basement of their home. From that starting point, the company has grown into a major firm that supports researchers worldwide with a reliable source of high-quality products and services.
Today, PBL Assay Science helps researchers solve difficult assay development and protein quantification problems and continues to serve as a trusted source for high quality, high sensitivity ELISAs as well as interferon proteins and antibodies. Its success can be attributed to its commitment to provide reliable products and uncompromising quality to its customers.
Now entering its 27th year, PBL Assay Science works hand in hand with industry, academic, and government researchers to help solve difficult assay development and protein quantification problems.
Known as a trusted source for high quality, high sensitivity ELISAs as well as interferon proteins and antibodies, PBL has expanded its assay services capabilities, including ultrasensitive cytokine detection services, and increased its human cell-expressed cytokine and growth factor offerings.
Whether you would like PBL to customize a multiplex assay incorporating your key analytes, to serve as an outside laboratory to run samples in confirmatory assays, or to express and purify a novel human cell-expressed protein, the company is here to serve your needs.
PBL’s beginnings are as a major provider of products, services, information, and know-how related primarily to interferons. The pioneering interferon research conducted by PBL’s founder, Sidney Pestka, M.D., and his many colleagues and collaborators reflects decades of exploration into interferon's applications in medicine.
Over the last two decades, PBL Assay Science has grown from start-up to well respected company, employing state-of-the-art technology in conducting assay services and manufacturing world-class products for scientists around the globe.
As its research, its products, and its services have moved beyond interferon into other cytokines and biological materials, PBL has grown into an Assay Science company with a broad knowledge base. Let PBL help you solve your most difficult problems.
