TīmeklisFor many years various tetrazolium salts and their formazan products have been employed in histochemistry and for assessing cell viability. For the latter application, the most widely used are 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), and 5-cyano-2,3-di-(p-tolyl)-tetrazolium chloride (CTC) for viability assays of … TīmeklisAfter that, the culture media and MTT were removed and replaced with absolute DMSO (200 µL) to dissolve formazan crystal as a final product of the MTT assay [59, 60]. The absorbance at 570 nm was ...
