Abstract
A magnetic support matrix for enzyme immobilization is prepared which comprises a porous, refractory inorganic oxide containing ferromagnetic particles dispersed throughout its interior and a polyamine cross-linked with an excess of a bifunctional reagent impregnated therein so as to furnish pendant functional groups. Such a magnetic support matrix does not otherwise substantially decrease loading of subsequently immobilized enzyme, nor in any other way substantially alter the properties of the immobilized enzyme system when compared to that prepared on a non-magnetic support.
