A) Presence of MTXMan1Ara5 (m/z 1261.7; M + NH4+) as detected (panel I) chromatogram; Panel II) Extracted ion) by ESI-LC/MS (positive ion) using borodeuteride-reduction and methyl iodide-permethylation of arabinan fragments. B) The EIC of m/z 1609.9 (M+NH4)+1 from Mlung-LAM corresponds to permethylated Man2Ara7 as well as permethylated Man4Ara4Lactate two peaks are present (panel I) in EIC shows the same ion from Left (II) and Right (III) peak showing the possible presence of both arabinan termini.
