General description

Affinity chromatography is a selective technique which takes advantage of specific molecular interactions, for example antigen and antibody. The Chromolith® WP 300 Protein A HPLC column is designed to monitor monoclonal antibody titer and yield determination from cell-culture supernatants. This analytical scale procedure helps to optimize the titer of monoclonal antibody for the optimal time for harvest of the monoclonal antibody products.

Chromolith® WP 300 Protein A 25-4.6 columns are made of monolithic silica with a characteristic bimodal pore structure.

Key Benefits:
—Rapid and accurate titer determination across a wide range of injection volumes
—Consistent binding efficiencies even at high flow rates
—Expanded column lifetimes
