TMB Stabilized Substrate is a stable, ready-to-use TMB (3,3', 5,5'-tetramethylbenzidine) color development substrate for localization of horseradish peroxidase-conjugated antibodies on dot blots and Western blots. It is easier to use than 4-chloro-1-naphthol (CN), which must be prepared immediately before use. TMB Stabilized Substrate comes premixed and fully diluted in a proprietary buffer containing less than 0.5% organic solvent.
