摘要:  组合抗体库技术是现代免疫化学研究的重要方法。它可以在体外构建大容量、高多样性的文库,将基因型和表型整合在筛选系统中实现表型的可复制,最终利用生物进化原理进行高通量筛选。这一技术可以在体外重建免疫系统,使抗体的筛选不受动物或生物组织的限制;通过分子克隆,可记录供者完整的免疫信息;通过重链和轻链的随机重组,可以提高文库的多样性,规避免疫耐受,揭示罕见抗体谱。随着免疫化学研究的不断深入,组合抗体库技术也在不断改进,出现了新的筛选策略,如基于自分泌的筛选系统和基于细胞-细胞相互作用的筛选系统。文章介绍组合抗体库技术的研究进展。

Abstract: Combinatorial antibody library is a key strategy in immunochemistry, which aims to establish libraries of large capacity and high diversity in vitro. It integrates the genotype and phenotype in the screening system to allow the molecule to self-replicate. It leverages the principle of biological evolution to perform high-throughput screening. This technology allows the reconstruction of an immune system in a test tube and empowers the antibody selection without the constraints of animals or organs. It records the donors’ immune response by molecular clone. The random recombination of heavy and light chains can avoid immunologic tolerance and discover rare antibodies. Due to the development of immunochemistry, the combinatorial antibody library technology keeps updating. Novel screening approaches have emerged, such as autocrine cell-based selection system and cell-cell interaction based system. Here, we introduce the development of combinatorial antibody library technology.
