Construction of CHO cell lines for high-efficient expression of recombinant proteins

Abstract

作为抗体药物的主力军,单克隆抗体(Monoclonalantibodies,简称mAbs)已成为世界生物制药行业的研究热点。本实验室已研制出具有开发为创新药物潜力的抗体需要进行大量表达用于临床前研究。抗体药物在开发阶段以及产业化阶段需要以稳定表达的方式进行生产,因此建立一个高效快速的稳定细胞株筛选平台对推进抗体药物的研发进程具有重要意义。 本研究首先构建了真核细胞表达质粒pNIDVD-GFP&mCherry,以绿色荧光蛋白GFP与红色荧光蛋白mCherry为荧光报告蛋白,将细胞株筛选流程可视化;以CHO-S、CHODG44、CHOK1为备选宿主细胞,开展包括宿主细胞的选择、转染方法的优化、加...A large amount of antibodies are needed since our lab have acquired numerous pharmaceutical antibodies against viruses such as Hepatitis B virus, Human respiratory syncytial virus and influenza virus. While proteins expressed by transient expression are always different in batch cultures, there is a need for stable cells to provide consistently stable products to the global market. The aim of the...学位:理学硕士院系专业:生命科学学院_细胞生物学学号:2162013115255
