    摘要: The invention provides methods of reducing fouling of ultrafiltration membranes in processes wherein virus particles are removed from aqueous solutions comprising virus particles and at least one protein by adding a surfactant or non-surfactant, non-ionic agent to the aqueous solution prior to filtration. The invention also provides methods to dissociate protein aggregates or to reduce the formation of protein aggregates by adding a surfactant or non-surfactant, non-ionic agent to the protein solution.
