Figure S4. MS Analysis of the Lipids Extracted from F Pili, Related toFigure 4
(A) Negative ion mode survey scan (600–780 m/z) of lipid extracts from whole cell membranes.
(B) Negative ion mode survey scan (600–780 m/z) of lipid extracts from purified pili treated with PLA2.
In all cases, phospholipids identity was confirmed by daughter fragmentation.
