CalB immo 8285 is an immobilized, recombinant Lipase B from Candida antarctica (CalB), produced by microbial fermentation with Pichia pastoris. It is a covalently immobilized preparation, suitable for water-based, solvent-based or solvent-free systems and can be used for regio- and stereoselective hydrolysis, esterifications and transesterifications. The lipase is immobilized onto our highly hydrophobic carrier, Lifetech ECR8285, an epoxy/butyl methacrylate co-polymer.

CalB immo 8285 was jointly developed and is co-marketed by c-LEcta and Purolite.
