PROBLEM TO BE SOLVED: To provide a substance high in binding specificity to immunoglobulin and extremely slight in the deterioration of its binding characteristics in undergoing sterilization treatment or during storage. SOLUTION: The immunoglobulin-binding peptide is represented by the following amino acid sequences(I), (II), (III) or (IV) or the like: (I) Arg-Ser-Thr-Leu-X1-X2-X3-Leu( wherein, X1 is Pro, Thr or Gln; X2 is Pro, Ala or Ile; and X3 is Ser or Gly ). (II) Ser-Gln-Ser-X4-Pro( wherein, X4 is Glu or Arg ). (III) Leu-X5-Gln-Pro-Leu( wherein, X5 is Ser, Leu or Val ). (IV) His-Leu-X6-X7-Ala-X8-X9-Ser( wherein, X6 is Pro or Arg; X7 is Thr or Lys; X8 is His or Leu; and X9 is Ala or Ser ). A carrier for refining immunoglobulin is such as to use the peptide, and a method for refining immunoglobulin involves using the peptide. COPYRIGHT: (C)2004,JPO&NCIPI
