Abstract
A gel-fiber glass (GFG) is a newly-formed sol-gel glass polymerized from tetramethoxysilane on the surface of activated glass wool fibers or activated fibrous glass. GFG is a support for trapped chemical or biochemical reagents. A thin layer of reagents trapped in gel glass during its preparation is present on the surface of a lattice of glass fibers. Columns for affinity chromatography were prepared from the GFG membranes with entrapped antigens or antibodies and were used to isolate different proteins, including tumor-associated antigens; GFG membrane demonstrated high effectiveness and stability, and can isolate proteins in extremely high amounts. The membranes can be used in diagnostic practice, generation of specific antibodies and therapy.
