Immobilised enzyme prods. for use in bio-sensors

摘要

Immobilised enzyme prods. comprise a dehydrogenase or reductase enzyme and its cofactor incorporated in a polymer matrix, where the cofactor is coupled to a polymeric spacer with a mol. wt. of 2600-20000. Also claimed is a process for the prodn. of a prod. as above which comprises adding an aq. soln. of the enzyme and its cofactor to an aq. monomer, prepolymer or polymer soln., and crosslinking the resulting soln..
