A new line of functionalised resins, called Amberzyme, designed to immobilize biocatalysts has been introduced by Rohm and Haas Advanced Biosciences. Amberzyme oxirane, the initial product to be marketed commercially, features an oxirane functional group that creates a covalent bond along with the amine terminus of an enzyme.
