3,3',5,5'-Tetramethylbenzidine (TMB) ≥99%, powder

Supplier: MP Biomedicals

3,3',5,5'-Tetramethylbenzidine is suitable as peroxidase substrate for use in ELISA procedures. The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620 to 650 nm. The TMB reaction may be stopped with 2 M H₂SO₄ (resulting in a yellow color), and read at 450 nm. A sensitive and specific reagent for the detection of blood, assay of hemoglobin, assay of peroxidases. It is useful in gel staining procedure for low levels of home-associated peroxidases and for enzyme immunoassay of horseradish peroxidase.
