Method for screening single chain antibody and single chain antibody

摘要

An object of the present invention is to provide a method for screening a single chain antibody having excellent separation efficiency and extremely high binding ability to an antigen and provision of a single chain antibody obtained by the screening method. Preparing a phage library that presents a single chain antibody, and preparing a single chain antibody that binds to the antigen bound to the multilamellar liposome from the phage library, A method for screening a single chain antibody that binds to an antigen, comprising the step of selecting the phage to be presented.
