T1 - Oligoepoxide-based monoliths: synthesis and application as affinity capillary column for enrichment of immunoglobulin G JF - Macromolecular chemistry and physics N2 - A series of new epoxide-based monoliths is synthesized by self-polymerization of polyglycerol polyglycidyl ether as porous support for affinity chromatography. Porosity and mean pore sizes are investigated as a function of the porogen ratio and analyzed by mercury porosimetry. The morphologies are visualized by environmental scanning electron microscope. With a particularly rigid monolith prepared with 75 vol% porogen (66% porosity and 12 µm mean pore size), a capillary column (0.5 mm ID) is prepared and directly functionalized with recombinant protein A to extract immunoglobulin G from rabbit serum.
