Understanding Downstream Process Development

Downstream process development concludes all steps following thee initial bioreactor production of a biotherapeutic - typically a monoclonal antibody, equinant protein, or vaccine. Thee goal is to isolate, purify, and formulate thee target estivule at high purity and yield while removing proces- related impurities (host cell proteins, DNA, endotothothothins) and product- relates (assets, charge variants, framents). Keunit operations included:
