Abstract
Systems and methods are described in which proteins are isolated from complex solutions in high yield and at high purity. Such systems and methods are carried out at ambient temperature and can be carried out at industrial scale with minimal energy requirements and minimal carbon footprint, using successive chromatographic separations that retain the protein or proteins of interest in flow-through fractions. At least one of the chromatography media used is selected to be capable of interacting with both contaminants and the protein of interest, however capacity of this media is selected such that the protein of interest is displaced and remains in the flow-through. Methods for isolation of IgG, albumin, and both IgG and albumin are provided.
