Web11 okt. 2016 · Chromatography Chromatography is based on the Greek word chroma, for colour. This technique is extensively used to separate mixtures into their components, purify compounds and also to test its purity. Chromatography works on the same principle as extraction, but one phase remains stationary and the other flows past. 3. WebGuide to Ion-Exchange Chromatography 5 Protocol Samples The SpinColumns are supplied dry and need to be rehydrated, the bed of ion-exchange resin with starting buffer allow 10-15 minutes for rehydration. After rehydration add a 2ml collection tube to the bottom of the SpinColumn and centrifuge for 1 minutes at 1000rpm.

Web10 apr. 2024 · Taking sodium chloride (NaCl) to represent inorganic salts in water, the working principle of ion exchange resin is as follows: Cation exchange resin: R—H + Na+ —— R—Na + H+. Anion exchange resin: R—OH + Cl- —— R—Cl + OH-. The general reaction formula of cation and anion exchange resin can be written as: RH + ROH + … Key steps in the ion exchange chromatography procedure are listed below: 1. An impure protein sample is loaded into the ion exchange chromatography column at a particular pH. 2. Charged proteins will bind to the oppositely charged functional groups in the resin 3. A salt gradient is used … Meer weergeven IEX chromatography is used in the separation of charged biomolecules.
