Figure 7.

Lipid pathway analysis and MALDI MSI heat maps for particular PE, PS, and PGP species annotated using Metaspace. PE and PS species appeared to be more intense in wild type stroke mouse brains, while PGP appeared to be more intense in knockout mouse brains. Possible side chain identifications are listed to the right of each respective heat map. Identifications that match other lipid species are bolded. Experiments were conducted on a15T FT-ICR mass spectrometer with a mass window of ±10 mDa. Mass-to-charge ratios in green indicate that samples were acquired in positive mode.
