Reduction with tris(2-carboxyethyl)phosphine (TCEP) enables the use of an S-sulphonate protecting group for thiol-mediated bioconjugation.
Résumé
Herein, we demonstrate the effectiveness of the water-friendly S-sulphonate group as an alternative to traditional thiol protecting groups for subsequent deprotection-bioconjugation reactions, under conditions that are compatible with the use of biochemical samples.
