title: Applications of MTT assay to primary cultured rat hepatocytes.
abstract: We investigated the optimal conditions for the application of the MTT assay to determine the viability of cell in primary cultures of rat hepatocytes. The optimal conditions were found to be: inoculation at cell density of 1.31 x 10(5) cells/cm2; concentration of 3-(4,5-dimethylthiazoyl-2-yl)-2,5-diphenyltetrazolium bromide (MTT) 0.12 mM; and MTT incorporation time, 2 h or more. We also found that insulin and glucocorticoid, which are usually added to the medium to maintain cell function, had no effect on the viability of the primary cultures of rat hepatocytes.
