| MS Comments: | Isolated TAMC and CD8+ T cells samples were dried using a SpeedVac. Acetonitrile (50%) was added to the tube for reconstitution following overtaxing for 30 s. Sample solution was then centrifuged for 15 min at 20,000g and 4°C. Supernatant was collected for LC-MS analysis. The mobile phase A contained 95% water/5% acetonitrile (v/v), 20 mM ammonium hydroxide, and 20 mM ammonium acetate (pH 9.0); phase B was 100% acetonitrile. The gradient was performed as follows: 0 min, 15% A; 2.5 min, 30% A; 7 min, 43% A; 16 min, 62% A; 16.1 to 18 min, 75% A; and 18 to 25 min, 15% A with a flow rate of 400 μl/min. The capillary of the electrospray ionization source was set to 275°C, with sheath gas at 45 arbitrary units, auxiliary gas at 5 arbitrary units, and the spray voltage at 4.0 kV. In positive/negative polarity switching mode, a mass/charge ratio (m/z) scan range from 70 to 850 was chosen and MS1 data were collected at a resolution of 70,000. The automatic gain control target was set at 1 × 106, and the maximum injection time was 200 ms. The top five precursor ions were subsequently fragmented, in a data-dependent manner, using the higher-energy collisional dissociation cell set to 30% normalized collision energy in MS2 at a resolution power of 17,500. |
