Protein Purification and Characterization

  • PROTEIN PRODUCTION, PURIFICATION, ANALYSIS

  • IBA offers a full complement of protein purification services. IBA’s expertise allows us to independently develop methods internally yet offer the flexability to employ a procedure that is designed by you. Our goal is to optimize your protein production through classic protein purification methods or new and innovative strategies for those challenging ligands. Protein purification is a stand alone service or can be employed to complement our assay method development, cell-based assay or antibody production services. As a value-added service endotoxin determination and removal as well as stable formulation is available.
