摘要: Proteins such as enzymes are attached directly to a polyamide or cellulose hydrate carrier. Attachment can be carried out by impregnation of the carrier with a protein solution. The carrier can be in the form of a membrane, and the polyamide can be nylon. Resulting carrier-bound proteins find utility as biocatalyst, as test strips or as chromatography materials. In a preferred embodiment, a polyamide or cellulose hydrate membrane carrier is impregnated with an enzyme selected from peroxidase, glucose oxidase, diaphorase and glucose dehydrogenase and then dried, coated with a luminol solution and again dried. The resultant membrane can be used for glucose determination by measuring chemiluminescence produced when the membrane contacts a glucose solution.
