Abstract
This invention provides a method for purifying and isolating a carboxyl-terminal peptide. A peptide bond between a lysine residue in a polypeptide and the adjacent amino acid residue is specifically cleaved on its carboxyl-terminal side. The resulting peptide mixture is then reacted with a solid carrier possessing on its surface functional groups capable of reacting and covalently bonding with free amino groups. Subsequently the peptide bond between the aminoterminal amino acid residue and the adjacent amino acid residue of each peptide is cleaned by acid treatment, and the peptides thus released from the solid carrier are isolated.
