A support matrix generally useful for the immobilization of biologically active proteins is made by coating with a polymeric alcohol a core support of titania or a carbonaceous pyropolymer deposited on a high surface area refractory inorganic oxide, cross-linking the alcohol, and converting a portion of the hydroxyl moieties to sulfonate esters. Such supports covalently bind enzymes and antibodies via a strong carbon-nitrogen single bond to give, for example, an immobilized antibody system extremely resistant to leaching of the antibody, the cross-linked alcohol, or of metals from the core support.
