TMB ELISA Peroxidase Substrate (3, 3', 5, 5' - Tetramethylbenzidine) is a chromogenic substrate used to visualize antibody reactivity in ELISA experiments. In the presence of peroxidases, TMB can act as an electron donor for the conversion of peroxides to water, changing the color of solution to a blue color equivalent to the degree of reactivity. This reaction can be halted with acid to change the TMB to yellow. TMB ELISA Peroxidase Substrate is ideal for investigators in Microbiology, Immunology, and Cancer research.

TMBZ is a chromogenic reagent utilized for peroxidase detection. It has been developed as an alternative to benzidine. Although the TMBZ solution is colorless, it turns bluish-green (lambdamax: 655 nm) in the presence of hydrogen peroxide and peroxidase. The structure of this bluish-green complex is thought to be a radical form of two oxidized TMBZ molecules. This peroxidase substrate is used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (ELISA). The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620-650 nm. The TMB reaction may be stopped with 2M H2SO4 (resulting in a yellow color), and read at 450nm.
