The present invention provides an anti-ovarian cancer bispecific antibody. Saidnantibody includes two polypeptide domains connected by a polypeptide linker, one isnanti-ovarian cancer antibody, or its Fab fragment, single complementarity determiningnregion (CDR) antibody or single chain Fv (scFv) and the other is anti-CD3 antibody,nor its Fab fragment, single CDR antibody or scFv. The present invention also providesnDNA sequences encoding said antibody, an expression vector containing said DNAnsequence, and a host cell containing said expression vector. |
