3,3',5,5'-Tetramethylbenzidine (TMB)

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.


  • This substrate will produce a soluble blue end product read at 370 nm or 655 nm. It's incubation time varies depending on the assay conditions.
