The resin used for the ion exchange column for this lab was DEAE-Sephacel resin. This resin is a weak anion exchange resin that allows for the attraction of proteins. The negatively charged proteins become attracted to the resin and the column is washed to remove unwanted molecules such as lipids, nucleic acids and carbohydrates.
