The commercial potential of monoclonal antibodies (mAbs) has been continuously increasing during the last years alongside with the number of approved mAb-based drugs and clinical trials. Despite their effectiveness and safety, the general access to this class of biopharmaceuticals is barred by high selling prices. Downstream processing is now considered the bottleneck in the manufacturing of mAbs.

DOWNSTREAM PROCESSING OF MONOCLONAL ANTIBODIES: CURRENT PRACTICES AND FUTURE OPPORTUNITIES Brian Kelley , Greg Blank , and Ann Lee 1.1 INTRODUCTION Monoclonal antibodies (mAbs) are now established as the most prevalent class of recombinant protein therapeutics. A bispecific monoclonal antibody (BsAb) is composed of fragments of two different monoclonal antibodies that bind to two different types of antigens [2]. Fusion proteins are produced from gene fusion techniques that allow the production of recombinant proteins featuring the combined characteristics of the parental products [3]. The BPI editors review some state-of-the-art alternatives in upstream and downstream monoclonal antibodies for drug substance bioprocessing as well as drug-product manufacturing. Friday April 09, 2021 Monoclonal Antibodies mAbs have evolved from being scientiﬁc tools derived from murine hybridomas in 1975 to biotherapeutic molecules based on humanized antibodies (see Glossary). The ﬁrst mAb for therapeutic use in humans was approved in 1986 and theﬁrst bispecific mAb (bsAb; catumaxomab) was approved in 2009 [1].

MAb capture was performed using MabSelect SuRe™ LX Impact of depth filtration on disulfide bond reduction during downstream processing of monoclonal antibodies from CHO cell cultures. O'Mara B (1), Gao ZH (1), Kuruganti M (1), Mallett R (1), Nayar G (1), Smith L (1), Meyer JD (1), Therriault J (1), Miller C (1), Cisney J (1), Fann J (1). Among the different development steps of a biotechnology process, a strong focus is made on the cell line generation and clonal selection, while downstream processing is considered well defined for molecules such as monoclonal antibodies. The downstream processing of monoclonal antibody after production in Bioreactors involve serial of steps (Figure 9B and C) . The purification process for the isolation of monoclonal antibody is by harvesting the cell cultured fluid from bioreactor using industrial continuous disc stack centrifuges, then clarification using depth and membrane filters.

This effort simplifies and accelerates early‐stage process development. Monoclonal antibodies (mAbs) are established as the most prevalent class of recombinant protein therapeutics. They can be expressed at high levels in cell culture, are typically highly soluble, and are relatively stable during processing. The nearly universal use of mammalian cell expression systems for mAb synthesis, combined with the selection of homologous, humanized mAb framework protein Downstream processing of Monoclonal Antibodies (MAbs): Challenges and troubleshooting Prasad Pasupuleti Hetero Drugs Ltd, India R ecent advances in mammalian cell culture technology has resulted in significant increases in upstream productivity, with antibody titers >5 g/L.

A Generic Manufacturing Strategy for Monoclonal Antibodies. Moving from high dilution to high purity is the principle of a good downstream process. Its priority is to concentrate and thus stabilize the product very early on and to remove critical impurities throughout the process.

Sathish Nadar Australian Research Council Training Centre for Biopharmaceutical Innovation, Australian Institute for Bioengineering and Nanotechnology, The University of Queensland, Corner College and Cooper Roads, Brisbane, Queensland, 4072, Australia. Monoclonal Antibody Structure and Impact on Downstream Processing The structure of mAb can be used to facilitate DSP. Based on their structure the mAb can have different charge in solution which can be manipulated to enable it bind more firmly unto an ion-exchange column. Multimodal chromatography: debottlenecking the downstream processing of monoclonal antibodies Review step [17] in this unit operation, which can be limited to accommodate the increasingly high titers coming from the upstream feedstocks [22].
