Disclosed is a tag for purification of peptides. The tag structure facilitates the easy cleavage of a bond formed between the tag molecule and a peptide to which it is bound under conditions which minimize, indeed preferably prevent, damage to the peptide. The tag molecules of the invention may be used to separate and/or purify a peptide from a mixture of peptides and/or other components.
