In the biopharmaceutical industry, the term "A Mab" (Monoclonal Antibody) has become synonymous with the modern era of targeted therapeutics. With over 100 Mabs approved by the FDA and a global market exceeding $200 billion, these large, complex proteins have revolutionized the treatment of cancers, autoimmune diseases, and infectious diseases. However, the journey from a hybridoma cell line to a commercially viable drug product is a gauntlet of scientific and engineering challenges. Focuses on cell culture optimization, including host cell
