ABSTRACT: Samples were analyzed using a nanoACQUITY UPLC system (Waters) coupled to a Q-Exactive HF-X high resolution accurate mass tandem mass spectrometer (Thermo) via a nanoelectrospray ionization source. Briefly the sample was first trapped on a Symmetry C18 180 micron x 20 mm trapping column (5 microliters/min at 99.9/0.1 v/v H2O/MeCN) followed by an analytical separation using a 1.7 micron AQCUITY HSS T3 C18 75 micron x 250 mm column (Waters) with a 90 min gradient of 5 to 30% MeCN with 0.1% formic acid at a flow rate of 400 nl/min and column temperature of 55 degC. Data collection on the HF-X MS was performed in data-dependent acquisition (DDA) mode with a 120,000 resolution (at m/z 200) full MS scan from m/z 375 to 1600 with a target AGC value of 3e6 ions and 50 ms maximum injection time (IT). The Top30 peptides were selected for MS/MS using a resolution of 15,000, max AGC of 5e4 ions and minimum AGC target of 2.25e3, max IT of 45 ms, collision energy of 27, an isolation width of 1.2 m/z and 20 s dynamic exclusion.
