Solution reagent kit TMB EASE

laboratoryliquidhydrogen peroxide

TMB (3, 3', 5, 5'-tetramethylbenzidine) is a chromogenic substrate for Horseradish Peroxidase (HRP). TMB produces a deep blue color during the enzymatic degradation of hydrogen peroxide by HRP, and the addition of a stop solution gives a clear yellow color that absorbs at 450nm. TMB EASE characteristics are: 1:1 replacement of carcinogenic 2mg OPD Aqueous based – no organic solvents (REACH Annex XVII compliant) Low lot-to-lot variation Specifications Available sizes: 100 mL, 500 mL, 1 L, bulk Format: Ready-to-use (RTU) Stability: 4 years Development time: 20-30 minutes Stop solution: 0.2 M H₂SO₄
