Abstract (en)
[origin: WO2013101855A1] A modified porous membrane comprising a polymer coating grafted to a porous membrane is described. The polymer coatings grafted to the porous membranes generally comprise a polymer of variable length of an electron beam (e-beam) reactive moiety, designated "poly-(A)x," a linkage group that forms a bond between the between the poly-(A)x, and a functional B group available to react with a chemical group on a biomolecule, wherein the polymer coating on the porous membrane facilitates the immobilization of a biomolecule, such as DNA, RNA, a protein, and an antibody, on the porous membrane. The compositions find use in immunoassays, in vitro diagnostic tests, point of care tests, techniques for the isolation of a biomolecule from a biological sample, and other methods that require the immobilization of a biomolecule on a porous membrane. Methods of making these modified porous membranes are also disclosed.
