MTT Test Protocol: MTT Test which is a colorimetric assay that plays a critical role in cell proliferation studies and cytotoxicity assays. This technique utilizes a yellow tetrazolium salt, MTT, which is reduced to purple formazan in the mitochondria of living cells. The amount of formazan produced directly correlates with the number of viable cells that enabling scientists to gauge cell viability and cytotoxicity accurately. … Continue reading MTT Test Protocol: Cytotoxicity Assays and Drug Screening
