摘要:
The disclosure provides a method for generation of humanized full length antibodies in mammalian cells. A library of humanized variants is provided with high, validated human framework diversity without requiring back-mutations to retain original affinity. Synthetic CDR encoding fragment libraries derived from a template antibody are ligated to human framework region encoding fragments from a human framework pool limited only to germline sequences from a functionally expressed antibodies. The vector comprises a nucleic acid sequence encoding HC framework region 4. No CDR grafting or phage display is required.
摘要(中):
本公开提供了在哺乳动物细胞中产生人源化全长抗体的方法。 人源化变体的文库提供了高度有效的人类框架多样性,而不需要反向突变保留原始亲和力。 将衍生自模板抗体的合成CDR编码片段文库连接到编码来自限制于来自功能性表达抗体的种系序列的人框架库的片段的人框架区。 载体包含编码HC框架区4的核酸序列。不需要CDR移植或噬菌体展示。
