Although chromatography remains the backbone of downstream workflows, selecting appropriate technologies to optimize processes can be challenging. Numerous resin options are available, and the fact that most biologics are large, complex, and inherently unstable further complicates development of a robust workflow. Because chromatography processes can alter a biologic in ways that could impair its intended therapeutic function, investment in process development is critical. Techniques such as design of experiments (DoE) can be used to identify the best approach during process…
