    摘要: The invention relates to a method of modifying a specific lysine residue in a polypeptide comprising at least two lysine residues, said method comprising (a) providing a polypeptide comprising a target lysine residue protected by a first protecting group, and at least one further lysine residue; (b) treating the polypeptide to protect said further lysine residue(s), wherein the protecting group for said further lysine residues is different to the protecting group for the target lysine residue; (c) selectively deprotecting the target lysine residue; and (d) modifying the deprotected lysine residue of (c).
