Hrp and dab
WebThe color produced by DAB is intensified by adding metals (nickel, copper, silver, and cobalt) that produce complexes that result in darker colored product and thus, enhance the sensitivity in staining. For chromogenic AP systems, the typical chromogen substrates are nitro blue tetrazolium (NBT) or 5-bromo-4-chloro-indolyl phosphate (BCIP). WebFor indirect detection, generally a HRP conjugated secondary antibody against the primary antibody is used. Staining is visualized using substrates such as DAB. To help scientists …
