用721-分光光度计测定过氧化氢酶活性的新方法
721-spectrophotometer——A new method of determining the activity of catalase
【摘要】 本研究采用两步法对过氧化氢酶活力进行测定。第一步是经典滴定法中的过氧化氢酶与底物作用,第二步采用过氧化物酶与剩余过氧化氢反应,氧供体(DH2)被氧化成棕色物,以棕色深浅反推过氧化氢酶活力单位。结果表明,该方法是一种灵敏、实用的测定过氧化氢酶活性的新方法。
【Abstract】 This research adopts two-step method to determine the activity of catalase.The first step is that catalase reacts with substrate in traditional titration method;The second step is that peroxidase reacts with residual hydrogen peroxide,DH2 is oxygenated to a brown material,according to the shade of brown color,activity unit of catalase can be deduced in reverse.These results indicate that it is a convenient,sensitive and practical method to determine the catalase activity.
