tetrazolium

Superoxide dismutase(SOD) in eggs can inhibit the photoreduction of nitro-blue tetrazolium (NBT).Thisreaction can be used to quantitatively determine the enzyme activities of SOD.

鸡蛋中的超氧化物歧化酶（SOD）可抑制氮蓝四唑（NBT）的光化还原，可SOD对NBT光化还原的抑制作为酶活性的定量测定。

Released LDH in culture supernatants is measured with a 30-minute coupled enzymatic assay, which results in the conversion of a tetrazolium salt (INT) into a red formazan product.

释放出的乳酸脱酶存在于培养物上清中,可用酶联检测法30钟测量。这种酶联致四唑盐（INT）转化成红色甲臜化合物。颜色形成的量与裂解细胞的数目成正比。
