Proteins

RayBiotech offers a diverse selection of over 6,000 proteins derived from mammalian, bacterial, parasitic, viral, and many other species. Our purified recombinant and native proteins serve a wide variety of applications including ELISA, EIA, Western blot, IP, functional assays, antibody production, protein-protein interaction studies, post-translational modification analysis, and protein arrays. With a relentless focus on innovation, we produce hundreds of novel and rare protein products each year.

RayBiotech Proteins

For proteins which are difficult to purify due to large size, toxicity in recombinant expression systems, low solubility (membrane-associated proteins), or instability on purification columns, RayBiotech provides an inexpensive solution. Our selection of unpurified cell extracts and culture supernatants are derived from bacterial or mammalian cells with the overexpressed gene of interest and protein expression verified by Western blot. These products are applicable for antibody validation (hybridoma screening or antibody pair screening), immunoprecipitation, reference samples in Western or ELISA, and many other uses. Look for catalog numbers starting with 230-1 (cell lysates) or 230-2 (supernatants).
