p-Iodonitrotetazolium Violet is used as a electron acceptor for the colorimetric assay of various dehydrogenases.

3,3',5,5'-Tetramethylbenzidine is suitable as peroxidase substrate for use in ELISA procedures. 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 2 M H2SO4 (resulting in a…
