Abstract: In one aspect, the present invention relates to an antigen-binding molecule specific for albumin and CD3 which may comprise two polypeptide chains, each polypeptide chain having at least four variable domains in an orientation preventing Fv formation and the two polypeptide chains are dimerized with one another thereby forming a multivalent antigen-binding molecule. On each of the two polypeptide chains the four variable domains may be arranged in the order VLA-VHB-VLB-VHA from the N-terminal to the C-terminal of the polypeptide. Compositions of the antigen-binding molecule and the methods of using the antigen-binding molecule or the compositions thereof for treatment of various diseases are also provided herein.

Abstract: A phagemid has been constructed that expresses an antibody fused to coliphage pIII protein. The phagemid is suitable for selecting specific antibodies from large gene libraries with small quantities of antigen. The antibody-pIII gene can be strongly repressed, so that it allows antibody libraries to be amplified without the danger of deletion mutants predominating. After induction, large quantities of the fusion protein may be expressed.
