Abstract:
Thin-layer chromatography (TLC) is a highly established convenient technique for lipid separation and partial characterization of neutral and acidic glycosphingolipids (GSLs) and phospholipids, in mixtures. Meanwhile, imaging mass spectrometry (IMS) is a promising tool for lipidomics. However, some lipid classes are detected more sensitively than others, which can lead to suppression effects when complex mixtures are analyzed. Therefore to analyze complex lipid mixtures, a precise separation into the individual lipid classes is necessary. Here we present our highly sensitive and convenient analytical technology that combines TLC and IMS, namely the TLC-Blot-MALDI-IMS method, to visualize whole lipids and individual molecular species with high sensitivity compared with common staining methods. This method allows for easy visualization of all lipids with a linear range of approximately one order of magnitude and precision <16% RSD, making it useful for differential display analysis of lipids.
