    摘要: Hydrophilic membrane particularly suited for blotting applications, preferably Western blotting. A pre-wet hydrophobic membrane substrate, preferably made of PVDF, is contacted with a monomer solution and subjected to a UV-initiated free radical polymerization step to render the substrate permanently hydrophilic. The resulting membrane exhibits low background fluorescence, high protein binding, excellent retention of protein sample spot morphology, and extended dynamic range (high signal-to-noise ratio, enhanced sample detectability). The membrane demonstrates comparable or higher performance in Western blotting applications than conventional nitrocellulose Western blotting membranes, particularly for protein detection at low sample concentrations, and is directly water-wettable, eliminating the need for an alcohol pre-wet step prior to use.

    摘要: This invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating in a layer which is less than the thickness of the membrane. Another object of this invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating to a predetermined and controlled depth from a first facial surface. Another object of this invention is to provide a general method to surface modify porous membranes with a free radical polymerized polymer coating into a pattern on one or both facial surfaces, the pattern maintaining its form to a controlled depth into the membrane. Membrane modification is spatially controlled through the use of a polymerization preventing agent (PPA), which prevents modification from occurring in defined spatially volumes of the membrane. The invention relates to porous membranes surface modified by the methods described.

    摘要: A composite liquid filtration platform including a composite filtration medium featuring an electrospun polymeric nanofiber layer collected on a porous membrane. When in use, the porous membrane acts as a prefilter used upstream from the polymeric nanofiber layer to remove particles from a liquid stream flowing through the composite filtration structure. The nanofiber layer, positioned downstream from the porous membrane, is used as the retentive layer for critical filtration to provide biosafety assurance, and is responsible for capturing microorganisms like bacteria, mycoplasma or viruses. The composite liquid filtration platform provided herein exhibits permeability advantages over conventional porous membranes or nanofiber mats spun on coarse non-wovens.
