The TMB/H2O2/HRP system revealed remarkable activity in catalyzing the reaction of the chromogenic substrate 3,3′,5,5-tetramethylbenzidine (TMB) and natural horseradish peroxidase (HRP) with H2O2, producing an oxidized product with an absorption at 450 nm. Under the optim...
Uptima TMB solutions are chromogenic reagents for peroxidase,designed for manual or automated ELISA techniques.They contain 3,3’(5)5’-tetramethylbenzidine(TMB),hydrogen peroxide(H2O2),and proprietary catalyzing and stabilizing agents.Reaction with peroxidase develops an intense blue color that can be...
The band at 43 kDa present in the WT and in the mutant corresponds to the reaction center-attached tetraheme cytochrome c (PufC). Both CcoP and CcoO are drastically reduced in the ctpA membranes compared with the wild type. These TMBZ bands turn green in the Coomassie Blue-stained gel (B...
J644-100ML Ready-to-use sensitive substrate for the detection of horseradish peroxidase activity. Absorbs at 450 nm (yellow end-product). Ideal for ELISA and solution assays. Soluble. Reaction Condition: 80 µg/ml in 1 M Sodium Acetate and 0.01% H2O2, pH 5.8. Stop with 1 M H2SO4. A...

Compared with TMB as the substrate, the synthesized TMB dots (TMBDs) show higher reaction activity in the presence of the same low-level Fe2+ and H2O2, resulting in highly sensitive sensing H2O2 down to 0.8nM. Additionally, the obtained TMBDs can well disperse in solution, while generally ...
