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)。
