Abstract:
1. An antibody-immobilized carrier comprising at least two antibody immobilized regions, wherein each of said antibody immobilized regions comprises a carrier binding peptide bound to the material of a carrier surface and to the C-terminus side of the heavy-chain variable region within a heavy-chain low-molecular-weight antibody, and a separate carrier binding peptide bound to the material of a carrier surface and the C-terminus side of the light-chain variable region within a light-chain low-molecular-weight antibody, wherein said heavy-chain low-molecular-weight antibody and said light-chain low-molecular-weight antibody within said antibody immobilized region recognize different antigens, wherein each of said antibody immobilized regions are configured such that an antigen may simultaneously bind said variable region of said heavy-chain low molecular-weight antibody and said variable region of said light-chain low molecular-weight antibody within said antibody immobilized region, wherein the material of the carrier surface is selected from the group consisting of a polystyrene plastic resin, a polycarbonate plastic resin, a polymethyl methacrylate plastic resin, a plastic resin obtained through hydrophilizing a polystyrene plastic resin, a plastic resin obtained through hydrophilizing a polycarbonate plastic resin, and a plastic resin obtained through hydrophilizing a polymethyl methacrylate plastic resin and wherein the carrier binding peptide is selected from the group consisting of SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18 and SEQ ID NO: 19.
