Analyzed on a UltiMate 3000 UHPLC system coupled with an Orbitrap Q Exactive HF mass spectrometer. A 90-min separation gradient was established with mobile phase A (2% ACN, 0.1% FA) and mobile phase B (0.1% FA in ACN) (0-8 min, 3%-6% B; 8-9 min, 6% B;9-25 min, 6%-12% B; 25-60 min, 12%-24% B; 60-70 min, 24%-35% B; 70-76 min, 35%-90% B; 76-85 min, 90% B; 85-86 min,90%-6% B; 86-90 min, 6% B), where the detection time for the MS was 25-85 min, and therefore also referred to as the 60 min effective gradient. Peptides were ionized at 2 kV. The MS was operated in DIA mode with an m/z scan range of 350 to 1,500 and a resolution of 60,000. The maximum injection time (IT), automatic gain control (AGC) target, and inclusion list were set to 20 ms,1 ×106, and 40 windows, respectively. High energy collisional dissociation (HCD) was employed for precursor ion fragmentation,where the normalized collision energy was 28. The maximum ion injection time of the MS2 was set to automatic and the resolution was 30,000.
