title: High-performance liquid affinity chromatography of beta-lactamase.
abstract: New silica and organic polymer-based, wide-pore, affinity chromatographic phases have been developed for beta-lactamase purification. The resins have been evaluated in terms of binding capacity, ligand coverage, protein recovery and long-term stability of activated resins prior to ligand attachment. The columns have been applied to the isolation of beta-lactamase from fermentation media. Protein purity following high-performance liquid affinity chromatography was assessed by polyacrylamide gel electrophoresis.
