(a) nMS of VAMP2 directly from liposomes containing seven different classes of lipids at a molar ratio that mimics the class-specific composition of ER. Different lipid-bound states are marked with the respective lipids. (b) Expanded view of the 3+ charge states showing up to six lipids (PC/PI) binding. Inset shows the negative stain image of the corresponding liposome.
