MCI-Gel® ion-exchange chromatography columns and resins for protein analysis and purification

The ProtEx columns are specifically designed to have lowest non-specific adsorption and high resolution for protein purifications. ProtEx columns are packed with a 5µm resin and available as strong cation exchanger (SP) and weak anion exchanger (DEAE). The CQA and CQK series of columns are high performance columns based on 10µm bead-size polyhydroxymethacrylate resins and available as strong and weak anion- and cation-exchangers (SP, CM, QA, DEAE). The CQA and CQK resins are available with a bead-size of 10µm and 30µm.

On this page you’ll find a list of the available columns and resins. For sample chromatograms of these columns you can download the PDF below.
