MXene as a novel cartridge for N-glycan enrichment

In this study, we applied MXene as column cartridge for N-glycan enrichment from human samples with a focus on the analysis of sialic acid linkages using a derivatisation protocol followed by glycan analysis via Matrix Assisted Laser Desorption Ionisation-Time Of Flight Mass Spectrometry (MALDI-TOF-MS). The MXene-based cartridge enriches a higher number of glycans (i.e., sialylated and bisecting N-glycans) when compared to the commercial HILIC columns. We demonstrate the strong potential of MXene as a stationary phase in MS glycomic analysis.
