The application of reverse-phase liquid chromatography (RPLC) in glycoproteomic analysis has attracted more and more attention. CD BioGlyco has a complete experimental system and powerful data analysis platform to meet the research needs of customers in glycan separation and purification. We are confident to provide customers with scientific help in the field of glycoproteomic analysis through a variety of strategies including RPLC.
RPLC uses hydrophobic interactions between biomolecules and ligands on chromatographic support to achieve separation. In the past decades, RPLC with C18 stationary phase has been widely used for peptide separations due to the relatively high hydrophobicity of peptides. In addition, C18-RPLC has also been used in large-scale glycopeptide separations. Since RPLC is a standard separation system, its compatibility with other proteomic research lines allows RPLC to be widely used in glycopeptide separation.
RPLC provides poor differentiation of glycan isomers, which limits the application of RPLC in glycoproteomic analysis. Therefore, RPLC is usually combined with various detection techniques for different research problems. Recent studies have reported that RPLC is coupled with electrospray ionization tandem mass spectrometry (ESI-MS/MS) for site-specific glycosylation analysis of highly heterogeneous glycoproteins in limited samples. RPLC has a great advantage of broad distribution because it is used in almost every bioanalytical research laboratory, making it an attractive platform for glycan analysis.
