  • Patent number: 9453066
    Abstract: Disclosed are: an Fc binding protein having increased stability with respect to heat, acid, and/or alkalinity compared with the wild type; a method for producing same; and a method for specifically isolating protein containing an Fc binding protein binding site using said Fc binding protein as a ligand for affinity chromatography. An Fc binding protein was obtained having increased stability with respect to heat, acid, and/or alkalinity compared with the wild-type human Fc receptor by means of substituting at least one specific amino acid residue in the extracellular domain of the wild-type human Fc receptor with another amino acid residue. The Fc binding protein is useful as a ligand for affinity chromatography for example by immobilizing in a solid phase.
