Application

3,3′,5,5′-Tetramethylbenzidine Liquid Substrate, Slow Kinetic Form, for ELISA has been used as a substrate for anti-bovine IgG-peroxidase conjugated antibody and for horse radish peroxidase-conjugated mouse anti-mouse IgG in Poly (ADP-ribose) binding assays.
Contains TMB in a mildly acidic buffer. The substrate is supplied as a one component ready to use solution. Rate kinetics are approx. 25% slower than traditional TMB formulations. Not recommended for membrane or immunohistochemical applications that require a precipitating reaction product.

XRCC1 accelerates repair of DNA single-strand breaks by acting as a scaffold protein for the recruitment of Polβ, LigIIIα, and end-processing factors, such as PNKP and APTX. XRCC1 itself is recruited to DNA damage through interaction of its central BRCT

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.
