    Abstract: A genetically modified mouse is provided, wherein the mouse expresses an immunoglobulin light chain repertoire characterized by a limited number of light chain variable domains. Mice are provided that express just one or a few immunoglobulin light chain variable domains from a limited repertoire in their germline. Methods for making bispecific antibodies having universal light chains using mice as described herein, including human light chain variable regions, are provided. Methods for making human variable regions suitable for use in multispecific binding proteins, e.g., bispecific antibodies, and host cells are provided. Bispecific antibodies capable of binding first and second antigens are provided, wherein the first and second antigens are separate epitopes of a single protein or separate epitopes on two different proteins are provided.

    Abstract translation: 提供遗传修饰的小鼠,其中小鼠表达免疫球蛋白轻链总谱,其特征在于有限数量的轻链可变结构域。 提供的小鼠在其种系中仅来自有限谱系的一个或几个免疫球蛋白轻链可变结构域。 提供了使用如本文所述的小鼠制备具有通用轻链的双特异性抗体的方法,包括人轻链可变区。 提供了适合用于多特异性结合蛋白(例如双特异性抗体)和宿主细胞的人可变区的方法。 提供了能够结合第一和​​第二抗原的双特异性抗体,其中第一和第二抗原是单个蛋白质的分离表位或两种不同蛋白质上的分离表位。
