阐明：生化学科学研究，能使过硫化氢分解成为水和氧   过空气氧化氢酶 來出自于牛肝 Catalase from bovine liver lyophilized powder, 2,000-5,000 units/mg protein Frequently Asked Questions Live Chat and Frequently Asked Questions are available for this Product. Components Catalase from bovine liver is a tetramer consisting of 4 equal subunits each with a 60 kDa molecular weight. Each of these subunits contains iron bound to a protoheme IX group. The enzyme will also strongly bind to NADP, where NADP and the heme group are within 13.7 angstroms. Application Catalase acts as a natural antioxidant to study the roles of reactive oxygen species in gene expression and apoptosis. It has also been used to protect against oxidative damage to proteins, lipids, and nucleic acids. Industrially, catalses have been used to remove hydrogen peroxide added to milk and cheese, in textile bleaching, and to examine its positive effects on the viability of DNA-repair mutants of E. coli. Biochem/physiol Actions 提高过阳极空气氧化氢的分解的，用来理论研究活性酶类氧在人类基因体现和组织凋亡中的功用的当然抗阳极空气氧化剂。 This product doesn′t need any activators, but it is inhibited by 3-amino-1-H-1,2,4 triazole, cyanide, azide, hydroxylamine, cyanogens bromide, 2-mercaptoethanol, dithiothreitol, dianisidnie and nitrate. Caution 不建立微冻水溶液。 Preparation Note 由缩二脲法测的血清质 Unit Definition 在 pH 7.0 和 25°C 下，一标准本品每半个小时应该分解成 1.0μmol H2O2，一同 H2O2 盐浓度从 10.3mM 降下来 9.2mM，这里是能够 A240 的缩减效率来衡量的。
