Abstract:
The kinetics of the nucleophilic addition reactions of divinyl sulfone to amino groups of glycine and model proteins was studied in aqueous solution at 30 degrees C. The rate constants for glycine, bovine serum albumin, and alpha 1-casein were (4.84 +/- 0.58) x 10(-1), (2.97 +/- 0.31) x 10(-2), and (2.38 +/- 0.49) x 10(-2) M-1s-1, respectively. Divinyl sulfone was proposed as a cross-linking reagent for the qualitative detection of protein association in solution. The cross-linking capacity of divinyl sulfone was compared to that of 1,3,5-triacryloylhexahydro-s-triazine.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
