应用

TMB是辣根过氧化物酶的底物。其可形成可溶性蓝色终产物,并可在370nm或655nm下读数。可以用0.5M H2SO4停止TMB反应(产生黄色溶液),并在450nm处读取数值。推荐用于ELISA(微孔)分析,不建议用于膜应用。
通过将测量的底物吸收值超过吸收最大值,3,3′,5,5′-四甲基联苯胺已在研究中用于证明,任何免疫酶测定的测量范围都可以被显著延长,而又不损害测定特征。3,3′,5,5′-四甲基联苯胺也已用于研究中,以了解具有过氧化物酶样活性的CuS凹面上层结构的形成。

注意

该底物对光非常敏感,应避免阳光或紫外光源直射。

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.

硝基蓝四唑(NBT)可与碱性磷酸酶底物5-溴-4-氯-3-吲哚基磷酸盐(BCIP)一起用于蛋白印迹和免疫组织染色程序。这些底物系统产生不溶的NBT二甲终产物,其颜色为蓝至紫色,可以通过视觉观察到。
