    摘要: PROBLEM TO BE SOLVED: To provide a humanized bispecific antibody having excellent functions such as exhibition of sufficient effects independently without improvement in structural stability and co-administration of activated lymphocyte (T-LAK).SOLUTION: The humanized highly functional bispecific antibody includes: an antibody that contains a humanized variable region (5H) of an H chain and a humanized variable region (5L) of an L chain of antihuman epidermal cell growth factor receptor 1 antibody 528 and a humanized variable region (OH) of an H chain and a humanized variable region (OL) of an L chain of anti-CD3 antibody OKT3, and has the following structure: an antibody in which a humanized diabody type bispecific antibody constituted of two kinds of single-stranded polypeptides of (OH5L) and (5HOL) is bonded with any one of the single-stranded polypeptides through a hinge region to two Fc regions of a human antibody.

    摘要: PROBLEM TO BE SOLVED: To provide a bispecific antibody that is structurally stable, and can show alone a sufficient effect without the co-administration of activated lymphocyte (T-LAK).SOLUTION: A humanized highly functional bispecific antibody includes humanized variable regions of the heavy chain (5H) and the light chain (5L) of an anti-human EGF receptor 1 antibody 528, and humanized variable regions (OH) of the heavy chain and humanized variable regions (OL) of the light chain of the anti CD antibody OKT3 and has one of the following structures: any one of the single-chain polypeptides of (OH5L)-(a peptide linker)-(5HOL), (OH5H)-(a peptide linker)-(5LOL), or (5L5H)-(a peptide linker)-(OHOL) is bonded to two Fc regions of a human antibody via each hinge region.
