Antibody reshaping is an effective way to reduce the immunogenicity while maintaining or improving the affinity of murine antibodies. This paper describe a new in vitro approach for rapidly reshaping murine antibodies by combining DNA shuffling with ribosome display. With the new method, a reshaping anti4-1BB single-chain antibody (scFv), Re-4B4-1 scFv, which bound to its antigen (4-1BB) specifically and strongly, was selected from a reshaping library. These results proved definitely the feasibility of the new designed approach for antibody reshaping.
