Imaging mass spectrometry of cuticular lipids of Drosophila melanogaster
Kaftan, Filip ; Vrkoslav, Vladimír ; Cvačka, Josef ; Svatoš, A.
The spatial distribution of cuticular lipids on the surface (head, thorax, abdomen and wings) of Drosophila melanogaster flies has been imaged and studied using MALDI-TOF mass spectrometry and scanning electron microscopy.
Methodology of lipid analysis of vernix caseosa using MALDI-TOF MS
Míková, Radka ; Vrkoslav, Vladimír ; Doležal, A. ; Plavka, R. ; Cvačka, Josef
This project is aimed to lipid analysis of intact molecules and optimization of MALDI-TOF MS method for these lipids.
Analysis of plant membrane lipids by RP-HPLC/HR-ESI-MS
Zábranská, Marie ; Vrkoslav, Vladimír ; Cvačka, Josef
Monogalactosyldiacylglycerols (MGDGs) and digalactosyldiacylglycerols (DGDGs) are glycolipids forming the major part of biological membranes in photosynthesizing organisms. The individual species differ from fatty acids linked to sn-1 and sn-2 possition on glycerol backbone. Complexity of their mixtures is increased by enzymatic or chemical oxidation of unsaturated species. The aim of this work was to develop and optimize RP-HPLC/HR-ESI-MS2 methods for analysis of oxidized and non-oxidized MGDGs and DGDGs in plant samples. MGDGs and DGDGs were isolated from Arabidopsis thaliana and Melissa officinalis.
Separation and identification of monogalactosyldiacylglycerols and digalactosyldiacylglycerols by RP-HPLC/ESI-MS
Krásová, Marie ; Cvačka, Josef
RP-HPLC/ESI-MS methods for analyzing complex mixtures of monogalactosyldiacylglycerols (MGDGs) and digalactosyldiacylglycerols (DGDGs) was developed. The methods allow separation and detection of more than 30 molecular species of MGDGs and more than 40 molecular species of DGDGs in plant samples.
