Abstract

The chemosensitivity of KB cells derived from oral epidermal carcinoma to various antitumor agents was analyzed using the MTT 3-(4,5-dimethyl-2-thiazoyl)-2,5-diphenyl-2H tetrazolium bromide) assay. Optical density (OD) for MTT assay was measured with dual wavelengths. The chemosensitivity of the drugs was evaluated by the 50% OD (OD50) of each drug concentration in the control group. Five platinum (Pt) drugs and 3 anthracycline (AC) drugs were used in this study. The chemosensitivity differed among the 5 Pt drugs. No significant difference was observed among the 3 AC drugs. A linear increase in OD corresponding to an increase in number of cells was observed. When 0.1 M sodium succinate (S.S.) was added to 0.4% MTT, the sensitivity increased five-fold compared to the control group without S.S. The MTT assay is a precise, rapid, easy and inexpensive experimental system useful for evaluation of antitumor drug sensitivity on tumor cell lines.
