Application

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

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.

Observational evidence suggests that infection with helminths protects against allergic disease and allergen skin sensitization. It is postulated that such effects are mediated by helminth-induced cytokine responses, in particular IL-10. We tested this hypothesis in a rural area of central
