Affinity chromatography is a method of separating biomolecule from a mixture solution, based on a specific binding interaction between an immobilized ligand and its binding partner.
Ion exchange chromatography (IEX) is a separation method based on their affinity to the ion exchanger. The two types of ion chromatography are anion-exchange and cation-exchange.
Hydrophobic interaction chromatography (HIC) separates molecules based on their hydrophobicity. HIC is a useful separation technique for purifying proteins while maintaining biological activity.
Reactivated beads are designed for covalent coupling of biomolecules. After coupling is performed, proteins of interest can be further purified.
