Figure 6.

MALDI MSI ion heat maps and intensity plots for DG species in knockout and control mouse brain tissue that have and have not undergone ischemic stroke. A) Three of the DG species annotated in Metaspace are far more intense in wildtype stroke mouse brains when compared to the other three conditions. B) One of the four DG species annotated in Metaspace appears to be relatively equal in abundance in both wild type and knockout mice after ischemia. Experiments were conducted on a15T FT-ICR mass spectrometer with a mass window of ±10 mDa Ion intensity bar and scale bar are displayed in the top panel
