ABSTRACT:
Graft copolymers comprising a poly-alpha-olefin base polymer selected from the group consisting of polyethylene, polypropylene, polystyrene, and compatible mixtures thereof, having grafted thereto an olefinic monomer. The grafted monomer is present in an amount effective to increase the amount of protein that will bind to the graft copolymer as compared with the base polymer.
Also disclosed are polymer/protein compositions comprising a graft copolymer having a protein immobilized on the surface thereof, processes for the preparation of the above-described graft copolymers and compositions, methods of immobilizing proteins, and methods of immunoassay based on such immobilization.
