Abstract

Abstract : A mild TCEP-based para -azidobenzyl cleavage strategy transforms reversible cysteine thiol labelling reagents into irreversible conjugates. Abstract : It has recently emerged that the succinimide linkage of a maleimide thiol addition product is fragile, which is a major issue in fields where thiol functionalisation needs to be robust. Herein we deliver a strategy that generates selective cysteine thiol labelling reagents, which are stable to hydrolysis and thiol exchange.
