Fractionation of BSA and lysozyme using ultrafiltration: effect of pH and membrane pretreatment

Selective transmission of a solute through membranes proves to be a challenge in ultrafiltration processes. This is because the transport of a solute through an ultrafiltration membrane does not depend on size alone, but on several other factors such as solute-solute and solute-membrane interactions. By manipulating physicochemical parameters and process variables (eg. pH, ionic strength, concentration of solute, etc.) and by membrane …
