TOYOPEARL AF-Formyl-650 is a reactive resin that requires activation for ligand attachment. Ligands may be coupled to the resin under mild conditions exclusively using primary amines. The ligand is bound to the resin by a stable secondary amine linkage. A wide variety of industrial enzymes have been immobilized on aldehyde-bearing supports. Consistent aldehyde content and physical properties are ensured from batch to batch.
