Abstract
The present disclosure provides methods for purifying products from a fluid. In some embodiments, provided purification methods use a combination of purification modes (e.g., protein A and ion exchange) operated in tandem, wherein at least one of the modes utilizes weak partitioning. In some embodiments, provided purification methods operate under robust conditions in which a degree of binding between a product and resin is maintained despite variations in operating parameters.
