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 1.31×105 cells/cm2 ; concentration of 3-(4, 5-dimethylthiazoyl-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) 0.12mM ; 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.
