Description Harvested sample is frozen by liquid N2 and resulting powder (100mg) are solved in 300uL methanol solution. 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% (0.0 to 1.0 min), 3 to 30% (1.0 to 26.0 min), 50 to 90% (26.0 to 41.0 min), 90% to 100% (41.1 to 46.0 min), 100% (46.1 to 51.0 min), 3% (51.1 to 58.0 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(150.0-2000.0); 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).
