The downstream chromatography industry is at the forefront of bioprocessing innovation, driving advancements in the purification and production of biopharmaceuticals. This eBook delves into the latest strategies and technologies revolutionizing downstream chromatography, offering insights into process intensification, optimizing chromatographic performance, and addressing host cell protein (HCP) challenges in monoclonal antibody (mAb) production.Process Intensification is a key focus area, aiming to enhance the cost-effectiveness and efficiency of protein A resins in bioprocessing. Traditional downstream chromatography represents a significant portion of manufacturing costs, with protein A steps contributing heavily to this expense. By implementing process intensification strategies, the industry can achieve substantial gains in productivity, reduce waste, and minimize facility space and energy consumption.
Optimizing Chromatographic Performance is another critical aspect covered in this eBook. The impact of packed bed height on efficiency and quality is explored, highlighting how modern chromatography resins with faster mass transfer can achieve higher dynamic binding capacities at shorter residence times. This optimization allows more cycles to be run per hour, improving productivity and reducing costs.
Addressing Host Cell Protein (HCP) Challenges in mAb production is essential for ensuring product quality and safety. Host cell proteins, expressed during the production of biotherapeutics, present significant obstacles in antibody purification. This paper discusses various approaches to mitigate HCP challenges, including the use of novel protein A-based agarose resins that enable purification under mild conditions, reducing aggregation and enhancing product purity.
In addition to these technical insights, the eBook also examines broader industry trends and challenges. Contract Development and Manufacturing Organizations (CDMOs) play a crucial role in adopting innovative bioprocessing technologies, but they must convince customers of the benefits of these new systems. Factors influencing HCP levels and the development of bioprocesses for cancer-fighting biosimilars are also discussed, providing a comprehensive overview of the current landscape in downstream chromatography.
