Abstract

Active proteins (enzymes) can be fixed on a collagenic support by covalent grafting. The immobilised enzyme is very stable, may be used repeatedly without loss of activity and has the active molecules on the surface so thar they are all accessible to the reacting species the collagenic support may be in the form of a film, fibre of foam.
