WebTMB reacts with HRP in a peroxide buffer to produce a water-soluble blue product that is suited for applications that require a large signal to noise ratio. 4CN produces a distinct blue-purple product that is useful for double staining despite the lack of sensitivity or stability afforded by TMB and DAB. DAB yields a brown colored precipitate. WebJun 2, 2014 · General notes. Abcam’s TMB ELISA Substrate (High Sensitive) detects horseradish peroxidase (HRP) activity and contains 3,3’,5,5’-tetramethylbenzidine in a mildly acidic buffer. The substrate is supplied as a ready to use solution. Unreacted substrate should be colorless or very light yellow in appearance.
