Description Sample is frozen by liquid N2 and resulting powder (250mg) are solved in 750uL 100% methanol solution. Cells are homogenized by TissueLyser (QUIAGEN, 25frequency, 2min) and centrifuged (15000rpm, 10min, 4 degree C). 20uL sample is injected into HPLC after 0.2um membrane filter treatment. HPLC conditions: Agilent 1100 series (Agilent), Column: TSKgel-100V (4.6 x 250 mm, 5 micrometer; TOSOH), Solvent: A; 0.1% formic acid aq. B; ACN (addition 0.1% formic acid fc.), Gradient: (B);3 to 97% (0.0 to 45.0 min), 97% (45.1 to 50.0 min), 3% (50.1 to 57.0 min), Column temp.: 40 degree C, Flow rate=0.5mL/min, PDA: 200-650 nm (2 nm step). FT-ICR-MS conditions: Filter 1: FTMS + c norm !corona !pi res=100000 o(100.0-1500.0); 2: ITMS + c norm !corona !pi Dep MS/MS Most intense ion from (1); 3: ITMS + c norm !corona !pi Dep MS/MS 2nd most intense ion from (1); 4: ITMS + c norm !corona !pi Dep MS/MS 3rd most intense ion from (1); 5: ITMS + c norm !corona !pi Dep MS/MS 4th most intense ion from (1); 6: ITMS + c norm !corona !pi Dep MS/MS 5th most intense ion from (1), Reject Mass List: 235.2000, 376.0400, 609.2800, 810.4100, 1123.6800.
