Extended Data Fig. 6: Isolation spectra of 4+ charge state lipid bound VAMP2 from synaptic vesicles mimicking vesicles. and Lipid bound/Apo-protein ratio.

a, Isolation spectra of 4+ charge state lipid bound VAMP2 from synaptic vesicles mimicking vesicles. b, Lipid bound/Apo-protein ratio calculated from area under the curve of apo-protein peaks and lipid bound protein peaks (and then total lipid bound area taken to get ratio) in nMS spectra of VAMP2 from synaptic vesicles mimicking vesicles.
