Reversed-phase separation methods for glycan analysis

Reversed-phase separation methods for glycan analysis

Reversed-phase chromatography is a method that is often used for glycan separation. For this, glycans are often derivatized with a hydrophobic tag to achieve retention on hydrophobic stationary phases. The separation and elution order of glycans in reversed-phase chromatography is highly dependent on the hydrophobicity of the tag and the contribution of the glycan itself to the retention. The c...

Reversed-phase liquid-chromatographic mass spectrometric N-glycan analysis of biopharmaceuticals

N-Glycosylation is a common post-translational modification of monoclonal antibodies with a potential effect on the efficacy and safety of the drugs; detailed knowledge about this glycosylation is therefore crucial. We have developed a reversed-phase liquid chromatographic-mass spectrometric method, with different fluorescent labels, for analysis of N-glycosylation, and compared the sensitivity...

Enantiomeric separation of Linezolid by chiral reversed-phase liquid chromatography.

A chiral liquid chromatographic method is developed for the enantiomeric resolution of Linezolid, (S)(-)-N-[[-3-(3-fluoro-4-(4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl] methyl] acetamide, an antibiotic in bulk drugs. The enantiomers of Linezolid are resolved on a Chiralcel OJ-RH column using a mobile phase system containing 150mM di-sodium hydrogen phosphate buffer (pH 4.5)-acetonitrile (86:14,...
