Home -> BioCat Partners: RayBiotech


Our partner RayBiotech, Inc., develops innovative, reliable research tools for the post-genomic age. Following the completion of the human genome sequence, researchers have been able to analyze the expression of a myriad of disease-related genes; however, many diseases result from abnormal protein expression, post-translational modification, or interaction with other biomolecules.

Founded in 2001, RayBiotech addressed the need for efficient, high-throughput protein analysis by introducing the first commercially available cytokine antibody array. Since then, the product lines have expanded to include hundreds of arrays and immunoassays for the efficient analysis of proteins involved in inflammation, angiogenesis, apoptosis, cell growth, and signal transduction.

The products are designed for the quantitative measurement of cytokines, chemokines, growth factors, phosphorylated targets, immunoglobulins and other immunological markers in a variety of species. They provide a fast, sensitive and economical method to quantify protein levels in different sample types including serum, plasma, urine, cell culture supernatants as well as cell and tissue lysates.
