Description:TMB is a noncarbinogenic analog of benzidine. It is typically used as a peroxidase substrate suitable 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 650 nm. The TMB reaction can be stopped with 2 M H2SO4(resulting in a yellow color) and read at 450 nm.
