Abstract
A method of producing an immobilized protein composite, i.e. enzymes such as glucose oxidase, on an alumina support, comprising modifying some of the free functional groups of the protein such as amino groups, by reaction with an acid or anhydride, depositing the modified protein on a porous inorganic support at controlled pH and temperature, and cross-linking remaining free functional groups of the protein with adjacent deposited protein functional groups to form interprotein peptide bonds. The resultant composite has long-term continuous use.
