XTT Cell Proliferation Assay Kit

Utilizes the second generation tetrazolium dye, XTT (sodium 2,3,-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)-carbonyl]-2H-tetrazolium inner salt), to measure cell growth, cytotoxicity, and apoptosis. It is a homogenous, highly sensitive, reproducible assay, and adaptable to high-throughput screening.
