In this review, we describe recent advances in antibody processing technology including: (1) development of proprietary cell lines; (2) improved expression systems optimized by selective technologies to boost underperformers; (3) improved protein-free and serum-free culture media; and (4) attention to glycosylation and other post-translational modifications. Advances in computer technology and sophisticated redesign of bioreactors have been major contributors to the dramatic improvements in antibody yields that have been documented in the last decade. Disposable bioreactor components are now widespread, resulting in improved yields, better quality product and lower costs for producers. Downstream innovations include (1) disposable devices for clarification and purification, (2) improved resins and ligands, and (3) new designs of hardware for improved performance. While there are numerous factors contributing to the increased yields that have been obtained, the most sustained of these is the introduction of disposable technologies on both the upstream and the downstream ends of the process. With the continuing introduction of improved computer technology and technological innovation, there is every reason to believe that quality and quantity of antibody products will continue to improve in the coming years, and supply will be adequate to meet the forthcoming needs of the industry.
