Zusammenfassung:Provided is an affinity chromatography carrier that maintains high immunoglobulin-binding capacity and high alkali resistance. An immunoglobulin-binding protein including at least one modified immunoglobulin-binding domain, the modified immunoglobulin-binding domain being a polypeptide consisting of an amino acid sequence of an immunoglobulin-binding domain selected from the group consisting of the B domain, Z domain, C domain, and variants thereof of Staphylococcus aureus protein A, in which at least one amino acid residue is inserted between positions corresponding to the 3-positions and position 4 of the amino acid sequence of the B domain, Z domain or C domain.
