目的 :建立检测肝癌细胞生长与药敏性的新方法。方法 :用XTT -PMS法检测肝癌细胞生长与药敏性。结果 :XTT -PMS法检测的适宜条件为XTT 0 2mg/mL ,PMS 5～ 5 0 μmol/L ,作用时间 2～ 6h。采用该法测定肝癌细胞药敏性的结果与MTT法相似。结论 :XTT -PMS法操作简单快速 ,测定结果准确可靠 ,可用于肝癌细胞生长与药敏性的检测 Objective: To establish a new method for detecting hepatoma cell growth and drug sensitivity. Methods: The growth and drug sensitivity of hepatoma cells were detected by XTT-PMS. Results: The optimum conditions for XTT-PMS detection were XTT 0 2 mg / mL and PMS 5 ~ 50 μmol / L for 2 ~ 6 h. Using this method to determine the sensitivity of hepatocellular carcinoma cells with MTT similar results. Conclusion: The method of XTT-PMS is simple and rapid, and the results are accurate and reliable. It can be used for the detection of hepatoma cell growth and drug susceptibility
