應用

3,3′,5,5′-四甲基联苯胺已用于:
  • Man-Rodosa-Sharpe(MRS)琼脂平皿的补充剂,在存在O2的条件下将乳杆菌菌落染成蓝色
  • 用作ELISA(酶联免疫吸附测定)的底物溶液
  • 定量中性粒细胞的髓过氧化物酶活性测定

3,3′,5,5′-四甲基联苯胺(TMB)是一种二氨基联苯胺的非致癌性取代物(Ames测试阴性)适合在ELISA实验中作为过氧化物酶底物。底物产生可溶性终产物,淡蓝色,分光光度检测在370或620-650nm可以读峰值。TMB反应能被2M H2SO4终止(产生黄色),在450nm处可读。一种高敏感,特异性试剂用于检测血液,血红蛋白实验,过氧化物酶实验。

生化/生理作用

3,3′,5,5′-四甲基联苯胺/ TMB可用作色原,加速过氧化物酶反应获取产物的进程。在食品和环境净化程序中,TMB可现场监测亚氯酸基消毒剂的游离氯(FAC)。

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
