  • Publication number: 20220363716
    Abstract: An objective is to provide an Fc-modified antibody or the like having a long serum half-life according to a CCAP method, more specifically, an antibody or the like where IgBP is bound to only one site, based on findings of the inventors. Provided is an objective antibody or the like by purification and production of an Fc-modified antibody or the like with a column bound to an Fc region of an antibody. Specifically, an antibody where only one of two binding sites of Fc is selectively modified is provided by allowing an IgBP-bound antibody produced by a CCAP method to adsorb to a carrier of an IgBP-immobilized column, or forming a state where only one Fc of an antibody is bound to an IgBP binding column and then adding a peptide reagent for CCAP to the column to perform a reaction of a CCAP method in the column.
