Fractionation of BSA and lysozyme using ultrafiltration: Effect of gas sparging

Abstract Fractionation of proteins by ultrafiltration is an interesting challenge. With a particular membrane, the protein – protein and protein – membrane interactions largely decide which protein passes through and which is retained. System hydrodynamics also affects protein fractionation as the transmission behavior of a protein is altered by concentration polarization. Therefore, disruption of the concentration polarization layer would help …
