Abstract

We show that latent oxalyl thioester surrogates are a powerful means to modify peptides and proteins in highly dilute conditions in purified aqueous media or in mixtures as complex as cell lysates. Designed to be shelf-stable reagents, they can be activated on-demand for enabling ligation reactions down to peptide concentrations as low as a few hundreds nM at rates approaching 30 M-1 s-1.
