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
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.
