琥珀酸脱氢酶(SDH,EC 1.3.5.1)广泛存在于动物、植物、微生物及培养细胞中,是线粒体的一种标志酶,位于线粒体内膜上,是连接呼吸电子传递链与氧化磷酸化的枢纽之一,同时也为多种原核细胞的产能呼吸链提供电子。 本试剂盒的测定原理为:SDH催化琥珀酸脱氢生成延胡索酸,脱下的氢通过吩嗪二甲酯硫酸盐(PMS)传递,还原2,6-二氯酚靛酚(DCPIP);DCPIP在600 nm处具有特征吸收峰,通过测定600 nm处吸光度的变化速率,反映DCPIP的还原速度,从而计算SDH的酶活性。
Succinate dehydrogenase (SDH, EC 1.3.5.1) is widely distributed in animals, plants, microorganisms, and cultured cells. As a marker enzyme of mitochondria, it is located on the inner mitochondrial membrane and serves as a crucial link between the respiratory electron transport chain and oxidative phosphorylation. In addition, it also supplies electrons to the energy-generating respiratory chains of various prokaryotic cells. The assay principle of this kit is as follows: SDH catalyzes the dehydrogenation of succinate to fumarate, and the released hydrogen is transferred via phenazine methosulfate (PMS) to reduce 2,6-dichlorophenolindophenol (DCPIP). DCPIP exhibits a characteristic absorption peak at 600 nm. By measuring the rate of change in absorbance at 600 nm, the reduction rate of DCPIP is determined, which allows for the calculation of SDH enzyme activity.
