Title
(EN) ANTIGEN-BINDING DOMAIN, AND POLYPEPTIDE INCLUDING CONVEYING SECTION
(ZH) 包含抗原结合结构域和运送部分的多肽
Abstract
(EN) The present invention pertains to: a polypeptide that includes an antigen-binding domain and a conveying section having an inhibitory domain for inhibiting the antigen-binding activity of the antigen-binding domain, and that has a half-life longer than that of the antigen-binding domain when existing alone; a production method and screening method for the polypeptide; a pharmaceutical compositioncontaining the polypeptide; a production method and screening method for a single-domain antibody the antigen-binding activity of which is inhibited by being associated with a specific VL/VH/VHH; anda library of fused polypeptides including a single-domain antibody the antigen-binding activity of which is inhibited by being associated with a specific VL/VH/VHH.
(ZH) 本发明涉及:包括抗原结合结构域和运送部分且具有比单独存在的抗原结合结构域更长的半衰期的多肽,其中所述运送部分具有用于抑制抗原结合结构域的抗原结合活性的抑制结构域;用于制备和筛选该多肽的方法;含有该多肽的药物组合物,用于制备和筛选通过与特定的VL/VH/VHH缔合而使其抗原结合活性受抑制的单结构域抗体的方法;以及包含通过与特定的VL/VH/VHH缔合而使其抗原结合活性受抑制的单结构域抗体的融合多肽的文库。
