  • Publication number: 20220295809
    Abstract: The present invention concerns a method for concentrating dairy proteins. The method includes producing and using negatively-charged ultrafiltration membranes to achieve high hydraulic permeability with low sieving coefficients. The method thus yields good protein concentration at a fast rate.
    Type: Application

  • Publication number: 20210253633
    Abstract: This disclosure provides a method for concentrating a solution of a macromolecule that is retained on at least two semi-permeable membranes that have different molecular weight cutoffs (MWCOs), the method comprising passing the solution through a hybrid configuration of said semi-permeable membranes staged in series in a single pass tangential flow filtration (SPTFF) apparatus. The method is applicable to the efficient concentration of biological macromolecules such as proteins, antibodies and nucleic acids.
