Cross-linked protein crystal technology in bioseparation and biocatalytic applications. Espoo 2004, Helsinki University of Technology. Abstract Chemical cross-linking of protein crystals form an insoluble and active protein matrix. Cross-linked protein crystals (CLPCs) have many excellent properties including high volumetric activity and stability. In this thesis CLPC technology was studied in bioseparation and biocatalytic applications. A novel immunoaffinity separation material, cross-linked antibody crystals (CLAC), was developed in this thesis for enantiospecific separation of a chiral drug, finrozole. Previously, the preparation of an antibody Fab fragment ENA5His capable of enantiospecific affinity separation of the chiral drug has been described.
