  • Title: Matrix-assisted laser desorption/ionization mass spectrometry of polysaccharides with 2',4',6'-trihydroxyacetophenone as matrix.
    Author: Hsu NY, Yang WB, Wong CH, Lee YC, Lee RT, Wang YS, Chen CH.
    Journal: Rapid Commun Mass Spectrom; 2007; 21(13):2137-46. PubMed ID: 17546658.
    Abstract:
    So far, there have been only a few matrices reported for detection of polysaccharides with molecular weight higher than 3000 Daltons by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). In this work, we found that 2',4',6'-trihydroxyacetophenone (THAP) is a good matrix for MALDI time-of-flight MS analysis of polysaccharides with broad mass range. Large polysaccharides, dextrans, glycoproteins and polysialic acids have been successfully detected by MALDI-MS with THAP as matrix.
