Supplementary Figure S8. MALDI-MSI data of mouse lung tissue administered with D9-choline and
U 13C-DPPC–containing Poractant alfa surfactant (labels administered 18 h prior to sacrifice). Ion
images of (a) m/z 796.6856 ([U13C-DPPC+Na]+), (b) m/z 756.5154 [PC32:0+Na]+ and (c) m/z 765.6079
([D9-PC32:0+Na]+). (d) Overlay image of [U13C-DPPC+Na]+ (red) and [D9-PC32:0+Na]+ (green).
Parts per million (ppm) mass errors are indicated in parentheses. All images were visualised using totalion-current normalisation and using hotspot removal (high quantile = 99%). DPPC = PC16:0/16:0. |
