General description

This product contains 3, 3′,5 ,5′-Tetramethylbenzidine (TMB) in a mildly acidic buffer. The substrate is supplied as a one component ready to use solution. Rate kinetics are approx. 40% faster than traditional TMB formulations. Not recommended for membrane or immunohistochemical applications that require a precipitating reaction product.

Application

3, 3′,5 ,5′-Tetramethylbenzidine Liquid Substrate, Supersensitive, for ELISA has been used as a substrate for peroxidase:
  • to determine synthesized hyaluronan and HAS2 (hyaluronan-synthesizing enzyme) expression by the transfectant[1]
  • to measure the levels of α-hemolysin toxin[2]
  • in imaging bound IgGs[3]

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 655 nm. The TMB reaction may be stopped with 2 M H2SO4 (resulting in a yellow color), and read at 450 nm.

This contribution deals with comparative studies on the chiral separation of thiazide diuretics using cellulose tris(3,5-dimethylphenylcarbamate) (Chiralcel OD-RH), cellulose tris(4-methylbenzoate) (Chiralcel OJ-R) and teicoplanin (Chirobiotic T) phases. All columns showed good chiral recognition ability for this class of compounds. Out

Due to the lack of sensitivity in current methods for the determination of fenoterol (Fen), a rapid LC-MS/MS method was developed for the determination of (R,R')-Fen and (R,R';S,S')-Fen in plasma and urine. The method was fully validated and was linear
