Proteins are different. Based on what protein you would like to purify and the conditions used, chromatography resins are selected to optimize purity and yield. Many bioprocess applications include three chromatography steps: capture to isolate, concentrate, and stabilize the protein. There is an intermediate step where bulk impurities are removed followed by polishing to achieve a final high-level purity. During method and process development, chromatography resins are selected and tested. In this guide, you can find help to select the resins suitable for your application.
