Antibody capture technologies for high-titer antibody production

doi:10.16085/j.issn.1000-6613.2018-1115

Abstract

Abstract:

Product capture from a cell culture broth is a key step in the production of antibodies and Fc-fusion proteins. With a rapid increase of large-scale animal cell culture techniques, capture techniques in antibody production have become the key technical bottleneck in monoclonal antibody productions. In this paper, core antibody capture methods, including protein A chromatography and cation exchange chromatography, have been reviewed in term of their history and applications. At the same time, peptide affinity chromatography, mixed-mode or multimodal chromatography, expanded-bed adsorption and sequential multi-column adsorption have been introduced to exhibit their great potentials in high-efficient antibody captures. Moreover, the factors affecting the capture and purification processes were analyzed while the problems that need to be solved to improve the technologies were discussed. Finally, perspectives into the development of antibody captures were discussed with focusing on the technological aspects of the chromatographic methods.

Key words: antibody, capture techniques, protein A chromatography, cation exchange chromatography, peptide affinity chromatography, mixed-mode chromatography, expanded-bed adsorption, sequential multi-column adsorption
