用可见光分光光度计测细胞内琥珀酸脱氢酶活性谢克勤，张磊，高树君，历保秋，孙克任（毒理研究室）用ＭＴＴ测定细胞内琥珀酸脱氢酶（ＳＤＨ）活性［１－３］，因用细胞培养板和酶标仪误差较大，不适于定量分析易挥发的毒物。现将我们研究的一种方法介绍如下。１材料和方... Intracellular Succinate Dehydrogenase Activity Measured by Visible Spectrophotometer Xie Keqin, Zhang Lei, Gao Shujun, Li Baoqiu, Sun Keren (Toxicological Research Laboratory) The intracellular succinate dehydrogenase (SDH) activity was measured by MTT assay ], Due to the use of cell culture plate and microplate error greater, not suitable for quantitative analysis of volatile poisons. Now we study a method described below. 1 Materials and methods ...
