The present invention relates to a peptide specifically binding to an Fc fragment of an immunoglobulin G (IgG), wherein the tryptophan (trp) at position 11 in the amino acid sequence of SEQ ID NO: 1 is an alanine By having an amino acid sequence substituted with an amino acid, the binding force to IgG can be controlled, and thus it can be utilized as a substrate for immobilizing an IgG having an excellent binding ability to IgG, as a monolayer membrane, or as an IgG purification column having excellent purification ability Lt; RTI ID = 0.0 > Fc < / RTI > |
