This video demonstrates the principle of separation of hydrophilic polar compounds using hydrophilic interaction liquid chromatography. This technique helps in the purification of various polar analytes, including N-glycans.
Protocol
1. Hydrophilic interaction chromatography and analysis of glycans Conditioning of UPLC instruments and preparation of mobile phases Prepare mobile phases including solvent A: 100 mM ammonium formate (pH = 4.4), solvent B: 100% acetonitrile, solvent C: 90% ultra-pure water (10% methanol), and solvent D: 50% methanol (ultra-pure water). Open the software to control the mobile phases. Wash UPLC instruments at flow rate of 0.2 mL/min (50% solvent B and 50% solvent C) balanci…
