Assay Designs

Assay Designs was a life science company that developed and manufactured immunoassay and detection kits for the global research market. Based in Ann Arbor, Michigan, the company offered a broad portfolio of ELISA kits, antibodies, and proteins focused on areas such as inflammation, oxidative stress, and cell signaling. In 2009, Assay Designs was acquired by Enzo Biochem for approximately $12.2 million and was integrated into the Enzo Life Sciences division. The company's products were widely used in academic and pharmaceutical research to quantify biomarkers and study cellular processes. The acquisition allowed Enzo to significantly expand its presence in the high-growth immunoassay market, particularly through Assay Designs' expertise in prostaglandins and cyclic nucleotides.
