Resumen: The last triennium has shown a significant contribution of high-performance thin-layer chromatography (HPTLC) to lipidomics. HPTLC separation in combination with radio- and/or ultraviolet-fluorescence (UV-FL) densitometry was the technique of choice for tracking the transport of phospholipids among different cellular compartments in a number of biological systems, e.g., Gram-negative bacteria, yeast membranes, endoplasmic reticulum/mitochondrial membrane interface, and also to monitor the lipid transfer activity of a protein. Likewise, a significant number of HPTLC methods were developed to determine variations in the content of different lipid classes and subclasses after using genetic knockouts of cells. Radiolabeled control cells and cells whose genes were deleted using genomic editing allowed to study by HPTLC the effect of the disruption of the related proteins on the corresponding biosynthetic pathways. As well, direct interface-based coupling of HPTLC to mass spectrometry (MS) using mostly electrospray ionization(ESI) and a variety of mass analyzers, has gained new momentum in this period. Obtaining a large amount of information online in a very short time from complex biological samples, and the structural identification of target and non-target, unknown lipids, make this technique a useful tool for lipidomics. Quantitative issues related to HPTLC-MS are also discussed in this work.
