WebAn ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface … WebIon exchange chemistry is based on the interaction that occurs between positively-charged particles and the negatively-charged phosphates that are present in DNA. The DNA binds under low salt conditions, and contaminating proteins and RNA can then be washed away with higher salt solutions.
