  • Antibody-immobilized carrier, method of producing antibody-immobilized carrier, and use of said antibody-immobilized carrier
    Patent number: 9598501
    Abstract: The present invention provides an antibody-immobilized carrier that can be used in antibody screening, a method of producing the antibody-immobilized carrier, and use of the antibody-immobilized carrier. Efficient antibody screening can be carried out particularly by an antibody-immobilized carrier including two or more antibody immobilized regions onto each of which a heavy-chain low-molecular-weight antibody and a light-chain low-molecular-weight antibody are separately immobilized, the two or more antibody immobilized regions each being included in an independent manner, the heavy-chain low-molecular-weight antibody including a heavy-chain variable region, the light-chain low-molecular-weight antibody including a light-chain variable region, the heavy-chain low-molecular-weight antibody and the light-chain low-molecular-weight antibody each being derived from an antibody recognizing a different antigen.

  • Peptide, Use of the Peptide, Method for the Production of the Peptide, Solid Support Having the Peptide Immobilized Thereon, and Method for Production of the Solid Support
    Publication number: 20140220626
    Abstract: Provided is a peptide containing a variable region and improved in production efficiency. The peptide contains a variable region to which an antigen-binding site is to be formed and has an amino acid sequence expressing a specific adsorption function to a solid phase at a site closer to the C-terminal than a heavy-chain variable region or at a site closer to the C-terminal than a light-chain variable region.
