	description	Harvested sample is frozen by liquid N2 and resulting powder (100mg) are solved in 500uL 80% methanol solution. Cells are homogenized by TissueLyser (QUIAGEN) and centrifuged (15000rpm, 10min, 4 degree C). 20uL of the supernatant (300uL) is injected into HPLC after 0.2um membrane filter treatment. HPLC conditions: Agilent 1100 series (Agilent), Column: TSKgel Amide-80 (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);80 to 45% (0.0 to 30.0 min), 45 to 35% (30.0 to 30.1 min), 35% (30.1 to 35.0 min), 35% to 80% (35.0 to 35.1 min), 80% (35.1 to 42.0 min), Column temp.: 40 degree C, Flow rate=0.8mL/min, PDA: 200-600 nm (2 nm step). Orbitrap-MS conditions: Filter 1: FTMS + c norm !corona !pi res=60000 o(150.0-2000.0); 2: FTMS + c norm !corona !pi res=7500 Dep MS/MS Most intense ion from (1); 3: FTMS + c norm !corona !pi res=7500 Dep MS/MS 2nd most intense ion from (1).

	title	PowerGet analysis for detection of all peaks (B4)
	description	Raw data files are converted to text file by MSGet software without cut off value and peaks are extracted from the text files by PowerFT with parameters (intensity cut off in peak detection=20000, margin of ion grouping in peak detection=5, peak selection filter is default, intensity cut off in peak assignment=1000). The replicates data are aligned by PowerMatch with blank data. The alignment is manually edited. Assigned peaks observed in multiple replicate samples are selected for annotation process.

	title	PowerGet annotation A1
	description	In annotation process, KEGG, KNApSAcK and LipidMAPS are used for primary database search. Peaks with no hit to these databases are then selected to secondary search using exactMassDB and Pep1000 databases. After the database search processes, each database hits are manually checked to assign a compound name or compound category name. In case of no compound name or compound category name can assign, predicted molecular formulas are used for the annotation. Peaks without predicted molecular formula are assigned as "unidentified" peak.
