Product Information
- TMB dihydrochloride
HRP and TMB - it takes two to tango! The enzyme horseradish peroxidase (HRP) has been isolated from the roots of the plant in commercially useful quantities since the nineteen-sixties. Today, HRP-coupled antibodies have become indispensable in immunoassays. The most popular chromogenic substrate for HRP is Tetramethylbenzidine (TMB), in particular in enzyme-linked Immunosorbent assays (ELISA). HRP converts TMB into a blue color that can be read spectrophotometrically at 650 nm. The HRP reaction can be stopped by adding sulfuric or phosphoric acid. This yields a yellow color that can be read at 450 nm.
