Cell Counting Kit-8 (CCK-8 / WST-8): A Reliable Tool for Cell Viability and Proliferation Assays
Introduction Cell viability and proliferation assays are essential tools in biomedical research, particularly in cytotoxicity testing, drug screening, and cell growth analysis. Cell Counting Kit-8 (CCK-8) is one of the most widely used colorimetric assays for quantifying cell viability, utilizing WST-8, a water-soluble tetrazolium salt. This article explores the principles, applications, advantages, and limitations of
