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.

鸡蛋中的超氧歧（SOD）以抑制氮蓝四唑（NBT）的光还原，以根据SOD对NBT光还原的抑制作为活性的定量测定。

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.

释放出的乳酸脱存在于培养上清中,用联检测法30分钟测量。这种联分析导致四唑盐（INT）转成红甲臜合。形成的量与裂解细胞的数目成正比。
