Provided is a peptide that specifically or selectively binds to human IgG. This peptide comprises an amino acid sequence consisting of 13 to 17 amino acid residues and is capable of binding to human IgG, wherein the amino acid sequence is represented by formula I: (X 1-3 )-C-(X 2 )-H-R-G-(Xaal)-L-V-W-C-(X 1-3 ), wherein, X each independently represents any amino acid residue except cysteine, C represents a cysteine residue, H represents a histidine residue, R represents an arginine residue, G represents a glycine residue, Xaa1 represents a glutamic acid residue or an asparagine residue, L represents a leucine residue, V represents a valine residue, and W represents a tryptophan residue. |
