Key Market Challenges

Manufacturing Complexities

Proteins are inherently complex molecules with precise three-dimensional structures. The manufacturing process must ensure the correct folding, post-translational modifications (e.g., glycosylation), and assembly of proteins to maintain their therapeutic efficacy. Protein therapeutics are often produced using genetically engineered cell lines, such as Chinese hamster ovary (CHO) cells or human cell lines. Developing stable and high-yielding cell lines is a time-consuming and intricate process. Upstream processing involves cell culture, where cells are grown in bioreactors and fed with nutrients to produce therapeutic protein. Maintaining optimal conditions for cell growth and protein expression is challenging and requires precise control of variables such as temperature, pH, and nutrient supply. Downstream processing involves the purification and isolation of the therapeutic protein from the cell culture. This step includes multiple chromatography and filtration steps to remove impurities, ensuring the final product's purity and safety. Stringent quality control measures are essential to verify the identity, purity, and potency of protein therapeutics. Analytical techniques must be highly sensitive and specific to detect and quantify impurities or variants.
