    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.

    Abstract translation: 一种蛋白质复合物,其包含(i)第一融合蛋白,其包含(a)第一多肽,其包含第一抗原结合位点和(b)与所述第一多肽的末端连接的第一结合蛋白; 和(ii)第二融合蛋白,其包含(a)包含第二抗原结合位点的第二多肽和(b)与第二多肽的末端连接的第二结合蛋白,其中所述蛋白质复合物包含氨基酸序列, 能够在第一多肽和第一结合蛋白之间和/或第二多肽和第二结合蛋白之间切割,以及制备双特异性抗体的方法及相关方法和组合物。
