Semiquantification of differentially expressed lipids in the ischemic brain. The relative contents of all lipids were determined using Xcalibur 4.0 with normalization to that of the internal spiking control SM(d18:1/12:0). The relative content levels of the 84 differentially expressed lipids in the MCAO brain was plotted in A–F to show changed lipids between 1 and 28 days post-MCAO. Due to the large disparity in the relative contents, even within the same groups of lipids, it was impossible to plot lipids from the same group together. The lipid contents changed the most between 1 and 7 days and subsided between 14 and 28 days post-MCAO.
