  • Publication number: 20230383013
    Abstract: The invention relates to porous polymeric cellulose prepared via cellulose crosslinking. The porous polymeric cellulose can be incorporated into membranes and/or hydrogels. In preferred embodiments, the membranes and/or hydrogels can provide high dynamic binding capacity at high flow rates. Membranes and/or hydrogels comprising the porous polymeric cellulose are particularly suitable for filtration, separation, and/or functionalization media.

  • Publication number: 20230149832
    Abstract: The present disclosure provides surface functionalized affinity membranes. The surface functionalized affinity membranes can provide increased binding capacity through improved coupling chemistries, ligand densities, spacer arm types, and spacer arm lengths. Methods of preparing the surface functionalized affinity membranes and methods of using the surface functionalized affinity membranes to isolate targets of interest, including nucleic acid molecules and proteins, from a sample are also provided.

  • Publication number: 20220040641
    Abstract: A membrane capsule for biological and chemical separations comprising a cassette comprising an upper surface and a lower surface adjoined by a cassette sidewall, an inlet and an outlet located on the upper and lower surfaces of the cassette, tubes fluidly connected to the inlet and the outlet, holes or slots in the tubes to facilitate separation, and a membrane wrapped, pleated, and/or spiral wound around each of the tubes. Methods of separation comprising flowing fluid flow through the inlet of the membrane capsule, allowing the fluid to permeate through the holes or slots of the tubes, separating biological and/or non-biological substances, collecting the fluid within a reservoir, and draining fluid from the reservoir.
