Therefore, it is necessary to elaborate regulatory protocols accompanying the increase in production and the nuances of the characteristics of this class of drugs. ĭrugs based on mAbs have been controlled by regulatory agencies around the world. The development of bioprocesses involving these production platforms can reap greater acceptance by the industry. MAbs production processes in wave or single-use bioreactor (SUBs) are characterized by flexibility and low operating costs when compared to the production processes in fixed stainless steel vats.

Improvements in cultivation are similar to those applied in other bioproducts that rely on culturing microorganisms or cells, requiring the development of a well-designed culturing process comprising the full range of control and associated operations that will support technical evaluations. In general, a process of commercial production of mAb begins with the generation of an mAb by immunizing an animal or by molecular biology methods involving the identification and optimization of the coding DNA sequence and the construction and identification of a stable high-producing clone. Production techniques have only had a sizable breakthrough due to molecular techniques. Large-scale production has revolutionized the market for monoclonal antibodies by boosting its production, making this a more practical method of production.
All process improvements provide a consistent and reproducible production of large quantities of mAbs at a moderate cost. Such advances have triggered improvements in production processes, allowing for the reduction of production costs and thus leading to an increase in the popularization of treatments with mAbs. Advances in molecular and cell biology for the development of more efficient antibodies have allowed advances in diagnostic and therapeutic areas. With the advent of genetic engineering, it has been possible to develop new methods to obtain monoclonal antibodies, both for improvement with regard to these humanized antibodies and for production models.

Various systems of production are used, including animal cells, microorganisms, plants, and mammary glands. Large-scale production has revolutionized the market for monoclonal antibodies by boosting its production and becoming a more practical method of production. For some years, new methodologies have advanced with new production processes, allowing scale-up production and market introduction. Additionally, there are studies and patents using a range of cells and microorganisms engineered for the production of mAbs at commercial scale. The first monoclonal antibodies (mAbs) have emerged from a survey of hybridomas, and nowadays mAbs are produced mostly from cultivations of these cells. Immunoglobulins are produced and secreted by B lymphocytes in response to the presence of antigens. They are able to identify or induce a neutralizing immune response when they identify foreign bodies such as bacteria, viruses, or tumor cells. Antibodies are glycoprotein structures with immune activity.
