Lipid identification in four biological samples. a The x- and y-axes show the experimental- and predicted retention times of newly identified lipid molecules in four biological samples. The lipid molecules from HEK cells, HeLa cells, mouse liver tissue, and mouse ear tissue are depicted in green, red, black, and blue, respectively. The Venn diagram to describe the overlap of unique lipid structures is shown in the right panel. b Result of lipid profiling in a mouse ear tissue. The x- and y-axes show the retention time and m/z, respectively. Each spot indicates the lipid molecules detected by the MS-DIAL program, the colors identify each lipid class. c Result of hierarchical clustering analysis for four biological samples and 415 binary variables of lipids. Yellow and blue indicate ‘detected’ and ‘not detected’ for each sample, respectively. The species between human cells and mouse tissues are clearly separated by the lipid properties
