Supplementary Figure S6. Ion distribution images for (a) [PC36:4+Na]+ (m/z 804.5514) and (b)
[PC38:6+Na]+ (m/z 828.5515) obtained from mouse lung tissue collected 6 h after administration of D9-
choline and U13C-DPPC–containing CHF5633. Parts-per-million (ppm) mass errors are indicated in
parentheses. (c) Magnification of the boxed region in (a) with selected bronchiolar regions outlined in
white boxes. (d) The corresponding H&E-stained tissue section with the same selected bronchiolar
regions outlined in black boxes. These data demonstrate the co-localisation of the polyunsaturated lipids
PC36:4 and PC38:6 with the bronchiolar regions of the lung. All MSI images were visualised using
total ion current normalisation and hotspot removal (high quantile = 99%). |
