    • The present invention is directed to diabody molecules and uses thereof in the treatment of a variety of diseases and disorders, including immunological disorders, infectious disease, intoxication and cancers. The diabody molecules of the invention comprise two polypeptide chains that associate to form at least two epitope binding sites, which may recognize the same or different epitopes on the same or differing antigens. Additionally, the antigens may be from the same or different molecules. The individual polypeptide chains of the diabody molecule may be covalently bound through non-peptide bond covalent bonds, such as, but not limited to, disulfide bonding of cysteine residues located within each polypeptide chain. In particular embodiments, the diabody molecules of the present invention further comprise an Fc region, which allows antibody-like functionality to engineered into the molecule.
    • 本发明涉及双抗体分子及其在治疗各种疾病和病症(包括免疫学疾病,感染性疾病,中毒和癌症)中的用途。 本发明的双抗体分子包含两个缔合以形成至少两个表位结合位点的多肽链,其可识别相同或不同抗原上相同或不同的表位。 另外,抗原可以来自相同或不同的分子。 双抗体分子的单个多肽链可以通过非肽键共价键共价结合,例如但不限于位于每个多肽链内的半胱氨酸残基的二硫键。 在具体实施方案中,本发明的双抗体分子还包含Fc区,其允许抗体样功能被改造成分子。
