    • The invention relates to immunoglobulin single variable domains directed against specific human CXCR4 epitopes (herein also referred to interchangeably as "compounds of the invention ", "amino acid sequences of the invention ", or "building blocks of the invention ") and polypeptides comprising them (herein also referred to as "polypeptides of the invention ", ''"'compounds of the invention ", or "constructs of the invention "). Furthermore, the present invention relates to nucleic acids encoding the compounds of the invention (also referred to herein as "nucleic acids of the invention" or '"nucleotide sequences of the invention")-, to methods for preparing the compounds of the invention; to host cells expressing or capable of expressing the compounds of the invention; to compositions, and in particular to pharmaceutical compositions, that comprise the compounds of the invention; and to uses of the compounds of the invention and the aforementioned nucleic acids, host cells and/or compositions, in particular for prophylactic, therapeutic or diagnostic purposes, such as the prophylactic, therapeutic or diagnostic purposes mentioned herein. The invention also relates to methods for generating immunoglobulin single variable domains against a target such as a cell-associated protein and constructs comprising said immunoglobulin single variable domains. The invention also provides immunoglobulin single variable domains obtainable by the methods of the invention. Specifically, the present invention relates to the generation of immunoglobulin single variable domains and constructs thereof by use of epitope walking with multimer libraries. More specifically, the present invention relates to the generation of immunoglobulin single variable domains derived from camelids directed against a particular epitope of a target, in particular against a target with multiple transmembrane spanning domains, including GPCRs and ion channels, by epitope walking with multimer libraries.
    • 本发明涉及针对特异性CXCR4表位的免疫球蛋白单可变结构域(本文还可以互换地称为“本发明的化合物”,“本发明的氨基酸序列”或“本发明的构建模块”)和包含它们的多肽 (本文还称为“本发明的多肽”,“本发明的化合物”或“本发明的构建体”)。 此外,本发明涉及编码本发明化合物的核酸(本文中也称为“本发明的核酸”或“本发明的核苷酸序列”) - 制备本发明化合物的方法; 宿主表达或能够表达本发明化合物的细胞; 包括本发明化合物的组合物,特别是药物组合物; 以及本发明化合物和上述核酸,宿主细胞和/或组合物的用途,特别是用于预防,治疗或诊断目的,例如本文提及的预防,治疗或诊断目的。 本发明还涉及用于产生针对靶的免疫球蛋白单可变结构域的方法,例如细胞相关蛋白和包含所述免疫球蛋白单可变结构域的构建体。 本发明还提供可通过本发明的方法获得的免疫球蛋白单可变结构域。 具体而言,本发明涉及通过使用多聚体文库进行表位走路来产生免疫球蛋白单可变结构域及其构建体。 更具体地说,本发明涉及通过用多聚体文库进行抗原表位的步骤来产生源自靶的特定表位的骆驼的免疫球蛋白单可变结构域,特别是针对具有多个跨膜跨越结构域(包括GPCR和离子通道)的靶 。
