说明：生化研究，能使过氧化氢分解为水和氧过氧化氢酶 来源于牛肝脏Catalase from bovine liverlyophilized powder, 2,000-5,000 units/mg proteinFrequently Asked QuestionsLive Chat and Frequently Asked Questions are available for this Product.ComponentsCatalase 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.ApplicationCatalase 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激活过氧化氢的分解，用于研究活性氧在基因表达和细胞凋亡中的作用的天然抗氧化剂。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不建议冷冻溶液。Preparation Note由缩二脲测定的蛋白质Unit Definition在 pH 7.0 和 25°C 下，一单位本品每分钟可以分解 1.0μmol H2O2，同时 H2O2 浓度从 10.3mM 降至 9.2mM，这是通过 A240 的降低速率来测量的。Related Categories1.11.1.6 Catalase, 1.x.x.x Oxidoreductases, Application Index, Diagnostic and Analytical Enzymes, Enzyme Class Index,General Metabolic Enzymes, General Metabolic Enzymes A-H, 代谢组学, 生化试剂, 细胞生物学, 酶、抑制剂和底物Less...Quality LevelELITEformlyophilized powdermol wttetramer mol wt ~250 kDaisoelectric point5.4storage temp.−20°CGene Informationcow ...
