Title A lipidome atlas in MS-DIAL 4
Description We formulated mass spectral fragmentations of lipids across 117 lipid subclasses and included ion mobility tandem mass spectrometry (MS/MS) to provide a comprehensive lipidome atlas with retention time, collision cross section and MS/MS information. Using human, murine, algal, and plant biological samples, we annotated and semi-quantified 8,051 lipids by MS-DIAL 4 (http://prime.psc.riken.jp/) with a 1–2% estimated false discovery rate, using the lipidomics standards initiative level 2 or 3 definitions.

Analytical Method Details Information

ID MS05
Title Method 5: Bruker timsTOF Pro DDA for mouse tissue lipidomics
Instrument LC, Bruker Elute UHPLC system; MS, Bruker timsTOF Pro
Instrument Type UPLC-QTOF-MS
Ionization ESI
Ion Mode Positive and Negative
Description Methanol, isopropanol, and acetonitrile of LC-MS grade were purchased from Wako. Ammonium acetate and EDTA were purchased from Wako and Dojindo, respectively. Milli-Q water was purchased from Millipore.

<LC Method>

The LC system consisted of a Bruker Elute UHPLC system. Lipids were separated on an Acquity UPLC Peptide BEH C18 column (50 x 2.1 mm; 1.7 µm) (Waters, Milford, MA, USA). The column was maintained at 45°C at a flow-rate of 0.3 mL/min. The mobile phases consisted of (A) 1:1:3 (v/v/v) acetonitrile:methanol:water with ammonium formate (5 mM) and 10 nM EDTA and (B) 100% isopropanol with ammonium formate (5 mM) and 10 nM EDTA. A sample volume of 0.5-3 µL, which depended on biological samples, was used for the injection. The separation was conducted under the following gradient: 0 min 0% (B); 1 min 0% (B); 5 min 40% (B); 7.5 min 64% (B); 12 min 64% (B); 12.5 min 82.5% (B); 19 min 85% (B); 20 min 95% (B); 20.1 min 0% (B); and 25 min 0% (B). Sample temperature was maintained at 4°C.

<MS Method>

Mass spectrometric detection of lipids was performed on a hybrid trapped ion mobility-quadrupole time-of-flight mass spectrometer (timsTOF Pro, Bruker Daltonics, Bremen, Germany). Data dependent MS/MS acquisition (DDA) was used. The parameters were MS1 mass ranges, m/z 200-2500 and MS2 mass ranges, m/z 50-2500; MS1 cycle time, 0.5 sec; MS2 accumulation 14 Hz ; collision energy, 30 eV; end plate offset, 500 V; capillary voltage, +4.5 kV/-4.2 kV; nebulizer pressure, 2 bar; dry gas, 10.0 l/min; dry temperature, 220°C/200°C; funnel 1 RF, 300 Vpp; funnel 2 RF, 200 Vpp/250 Vpp; multipole RF, 200 Vpp; deflection delta, +70 V/-70 V; quadrupole ion energy, 6 eV/5 eV; collision transfer energy, 14 eV/15 eV; collision RF, 1100 to 1800 Vpp stepping; transfer time 45 to 75 µs stepping; pre-pulse storage, 10 µs/5 µs; intensity threshold, 31cts.; exclusion time of precursor ion, 0.2 min. The mass calibration was automatically performed using 5 mM sodium acetate calibration solution.
