Cleave bonds

WebAbstract. Disulfide bonds can be cleaved at an alkaline p H by treating a protein with excess of a reagent disulfide in the presence of catalytic amounts of thiol. The cleavage products are stable and can be isolated; they contain the mixed disulfide between the reagent and the exposed thiol groups of the protein.
