WebAbstract. Disulfide bonds can be cleaved at an alkaline pH 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. http://webhost.bridgew.edu/fgorga/proteins/disulfide.htm WebThis is because the disulfide bonds (established during the initial folding of the protein, during its synthesis), reduce the number of possible ways to "misfold".
