Optimization of covalent immobilization of Recombinant Prokaryotic Lectins on CIMmic™ platform
Pre-activated CIMmic™ Monolithic Columns are used as a basis for preparation of small volume affinity chromatographic columns as well as enzyme reactors. Small bed volume and flexible design makes them a powerful tool for screening purposes and immobilization protocol optimizations. Range of covalently bound ligands is wide and includes diverse set of proteins, peptides, nucleotides and other affinity ligands. The covalent nature of the bond between the ligand and matrix reduces leaching and improves stability and reusability. Reaction conditions must cater to their specific physiochemical nature.
Successful preparation of an affinity column includes a decision on the appropriate matrix chemistry and determination of an optimal immobilization protocol. Presented case study explores the basics of a coupling protocol optimization using covalent immobilization of Recombinant Prokaryotic Lectins (RPL-Gal1) on CIMmic CDI-0.1 and CIMmic ALD-0.1 columns, as an example. Carboxy imidazole (CDI) and aldehyde (ALD) activated CIMmic™ columns are used for covalent immobilization of amine or thiol containing molecules.
