  • Patent number: 10611817
    Abstract: The present invention addresses the first problem of providing an Fc-binding protein having improved stability, especially stability to heat and acid, of the Fc-binding protein, a method for producing this protein, and an antibody adsorbent using this protein. The present invention also addresses the second problem of providing a method that makes it possible to identify the presence or absence of glycosylation of an antibody, and a material to be used in this method. The first problem is solved by an Fc-binding protein having improved stability to heat and acid obtained by substituting amino acid residues at specific positions in the extracellular domain within human Fc?RIIIa with other specific amino acids, a method for producing this protein, and an antibody adsorbent using this protein. The second problem is solved by using an adsorbent capable of specifically adsorbing an antibody having a sugar chain, the adsorbent being obtained by immobilizing human Fc?RIIIa on an insoluble carrier.
