WebSTOP Solution is a proprietary solution used to terminate the peroxidase/TMB reaction for ELISA applications. The TMB substrate reacts with immobilized horseradish peroxidase (HRP) conjugated secondary antibodies to produce a blue solution. Color intensity is an indication of analyte level. 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.
