Determination of Significance：
Superoxide dismutase (SOD, EC 1.15.1.1) is a kind of metalloenzyme widely found in organism. It is an important oxygen radical scavenger and can catalytic disproportionation of superoxide anion to form H2O2 and O2. SOD is not only the superoxide anion scavenging enzyme, but also the main H2O2 producing enzyme, which plays an important role in the biological antioxidant system.
Measurement Principle：
Superoxide anion (O2-) is produced by the xanthine and xanthine oxidase reaction system. O2- can reduce blue tetrazole to form blue formazan, which has absorbance in 560 nm. SOD can remove O2- and inhibit the formation of methionine. The darker the blue color of the reaction solution, the lower the activity of SOD. The lighter the blue color of the reaction solution, the higher the activity of SOD.
Self Provided：
Spectrophotometer, table centrifuge, transferpettor, 1 mL glass cuvette, mortar/homogenizer/cell ultrasonic crusher, ice and distilled water.

试剂四是拿到手之后自己加蒸馏水溶解嘛2022-10-05 20:42:27
Administrator您好，试剂四是液体，需要用蒸馏水稀释成工作液去使用的
试剂二离心多久加蒸馏水2022-08-21 15:17:53
Administrator您好，瞬时离心后混匀去使用就行，如果离心机是必须要设置时间的离心设置最低的时间就行
您好，纯蛋白可以用这个试剂盒做酶学性质分析嘛？2022-07-15 21:39:58
Administrator如果是重组蛋白，蛋白需要做复性处理，有的重组蛋白是没有活性的
