Abstract:
A polypeptide linker comprising an antibody-binding region and an enzyme cleavage region, and related compositions, kits, and methods of using same.
Abstract:
Provided is a protein complex including a bi-specific antibody, and a method of preparing the protein complex, which can provide a system that simultaneously targets two antigens.
Abstract:
A protein complex comprising (i) a first fusion protein comprising (a) a first polypeptide that comprises a first antigen-binding site and (b) a first binding protein linked to a terminus of the first polypeptide; and (ii) a second fusion protein comprising (a) a second polypeptide that comprises a second antigen-binding site and (b) a second binding protein linked to a terminus of the second polypeptide, wherein the protein complex comprises an amino acid sequence that enables cleavage between the first polypeptide and the first binding protein, and/or between the second polypeptide and the second binding protein, as well as a method for preparing a bi-specific antibody and related methods and compositions.
