WebFurther, the combination of two chromogenic substrates permits the simultaneous detection of coliform bacteria and E. coli. Coliform bacteria detection: The substrate Salmon-GAL is used for the detection of β-D-galactosidase activity, which is characteristic for coliform bacteria. This interaction results in a pink to red color of the WebChromogenic substrates for western blotting with HRP. 3,3′,5,5′-tetramethylbenzidine (TMB), with a molecular weight of 240.4, is most often used as a substrate for HRP in ELISAs. However, in the presence of HRP and peroxide, a water-soluble blue product is generated that can be precipitated onto a membrane. Thermo Scientific 1-Step TMB ...
