  • Title: Particular matrix for fast atom bombardment mass spectrometric analysis of phenolic glycolipid antigens isolated from pathogen mycobacteria.
    Author: Rivière M, Fournié JJ, Vercellone A, Puzo G.
    Journal: Biomed Environ Mass Spectrom; 1988 Oct; 16(1-12):275-8. PubMed ID: 3072032.
    Abstract:
    Phenolic glycolipids play a key role as an antigenic probe for serodiagnosis of some human pathogen mycobacterial infections. The lipidic part which corresponds to a phenolphthiocerol dimycocerosate molecule, and the presence of partial O-methylated sugars, confer a high hydrophobicity to this kind of molecule. Fast atom bombardment (FAB) mass spectrometric analysis with standard matrices such as glycerol or thioglycerol was unsuccessful. Using a new matrix--monobutyltriethylene glycol--FAB analysis allows molecular weight determination and partial structural elucidation of the saccharidic and the lipidic part of those compounds.
