Tetramethylbenzidine (TMB) Test: # Principle, Reagent & Procedure

WebAug 24, 2024 · As mentioned above, the measurement of the concentration of proteins in an ELISA well is based on a colorimetric reaction. Most commonly, this is a blue reaction that results from the reaction of HRP with its substrate, 3,3′,5,5′-Tetramethylbenzidine (TMB). The addition of hydrochloric acid, which stops the reaction, turns the solution yellow. Web3,3′,5,5′-Tetramethylbenzidine (TMB) is a noncarcinogenic substitute (Ames test negative) for benzidine 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. commissioning test中文
