General description

3,3′,5,5′-Tetramethylbenzidine (TMB) is an electrochemical substrate for low level detection of horse radish peroxidase (HRP). It is a highly sensitive and dual function substrate, since it produces both soluble and insoluble reaction products. It has rapid reaction rate and it is suitable for on-line kinetic analysis. It does not possess carcinogenic properties.

Application

3,3′,5,5′-Tetramethylbenzidine Liquid Substrate, Super Slow, for ELISA has been used as a substrate for enzyme linked immunosorbent assay (ELISA).
Contains TMB in a mildly acidic buffer. The substrate is supplied as a one component ready to use solution. Rate kinetics are approx. 60% slower than traditional TMB formulations. Not recommended for membrane or immunohistochemical applications that require a precipitating reaction product.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

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.
