Applicazioni

3,3′,5,5′-Tetramethylbenzidine (TMB) is a peroxidase substrate suitable 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 620-650 nm. The TMB reaction may be stopped with 2 M H2SO4 (resulting in a yellow color), and read at 450 nm.
3,3′,5,5′-Tetramethylbenzidine dihydrochloride has been used as a substrate for the
  • anti-mouse IgG (? specific) horseradish peroxidase-conjugated antibody in the ELISA of mice sera
  • anti-mouse peroxidase antibody in the protein tyrosine phosphatase assay of naive and effector T cell lysate
  • in enzymatic hydroperoxide (EH) assay and in prooxidants–antioxidants balance (PAB) assay of serum samples from diabetic patients

We certify that protamine-gold nanoclusters (PRT-AuNCs) synthesized by one-pot method exhibit peroxidase-like activity. The catalytic activity of PRT-AuNCs followed typical Michaelis-Menten kinetics and exhibited higher affinity to 3,3',5,5'-tetramethylbenzidine (TMB) as the substrate compared to that of natural horseradish peroxidase.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
