Claim 24:
25. The method of claim 22, wherein the S-protected peptide is obtained by
re-protecting protecting groups of SH groups of a linear peptide having two or more SH groups as functional groups on the peptide, in which an N terminal amino group is optionally protected, and all of a C-terminal carboxy group and other functional groups on the peptide are protected, with an S-type protecting group, or
protecting same with an S-type protecting group in advance to obtain a peptide in which all SH groups are protected by formation of a temporary S—S bond with the S-type protecting group in (1-B), and
removing the protecting groups of all functional groups other than the SH group protected by the temporary S—S bond in the peptide in (1-A).
