Study IDST002335
Study TitlePathogenic Auxilin mutations affect lipids that are critical to Synaptojanin function
Study SummaryMass spectrometry was performed on heads of 15DO flies homogenized in 100 µl D-PBS (Dulbecco’s phosphate-buffered saline without Mg2+ and Ca2+) by Lipotype. Fifteen fly heads were pooled from three independent crosses for each analysis, and mass spectrometry was performed on n=7 for wild-type, n≥4 analyses for dAuxWT/WT, dAuxRG/RG, dAuxWT/F956x and dAuxRG/F956x and n=3 for dAuxWT/F956x and dAuxRG/F956x overexpressing Synj.

Sample Preparation:

Sampleprep ID:SP002429
Sampleprep Summary:Lipids were extracted using chloroform and methanol (1). Prior to lipid extraction, samples were spiked with lipid class-specific internal standards. After drying and resuspending in an appropriate MS acquisition mixture, lipid extracts were infused directly in QExactive mass spectrometer (Thermo Fisher Scientific) with TriVersa NanoMate ion source (Advion Biosciences). Samples are analyzed in both positive and negative ion modes, with MS resolution Rm/z=200=280000 and MSMS resolution Rm/z=200=17500, in a single acquisition. Sample preparations and analysis were done by Lipotype. (1) Sampaio, J. L. et al. Membrane lipidome of an epithelial cell line. Proceedings of the National Academy of Sciences 108, 1903–1907 (2011).
