Sample Preparation:

Sampleprep ID:SP000099
Sampleprep Summary:Suspentions softly centrifuged, buffer removed, amonium bicarbonate added, metabolites extraxted with chloroform/methanol (2:1, v/v), vortexed, centrifuged, aqueous layer dried in vacuum concentrator, derivatization with methoxyamine in pyridine, N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA), and 1% trimethylchlorosilane (TMCS)
Sampleprep Protocol Comments:Cell suspensions were softly centrifuged (230 × g for 5 min) and as much buffer as possible was removed. Then, 170 µL of 150 mM ammonium bicarbonate was added to the cell pellet and the cell suspensions were transferred to 2 mL micro-centrifuge tubes for extraction. Subsequently, the water soluble metabolites were extracted with four volumes of chilled (-20°C) chloroform/methanol (2:1, v/v). After vortexing, the samples were centrifuged (12,000 × g for 5 min) and the upper (aqueous) layers containing water-soluble metabolites were transferred into glass vials, followed by drying in a vacuum concentrator. For the derivatization, 20 µL of methoxyamine in pyridine (30 mg/mL) were added to each sample, followed by incubation at 37°C with shaking for 90 min to protect carbonyl groups. Next, 80 µL of N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) with 1% trimethylchlorosilane (TMCS) were added to each vial, followed by incubation at 37°C with shaking for 30 min to derivatize hydroxyl and amine groups. The samples were then allowed to cool to room temperature.
Processing Method:Homogenization
Extraction Method:The water soluble metabolites were extracted with four volumes of chilled (-20°C) chloroform/methanol (2:1, v/v). After vortexing, the samples were centrifuged (12,000 × g for 5 min) and the upper (aqueous) layers containing water-soluble metabolites were transferred into glass vials, followed by drying in a vacuum concentrator.

Chromatography:

Chromatography ID:CH000096
Chromatography Summary:Agilent 7890A gas chromatograph with a HP-5MS gas chromatography column using Chemstation
Chromatography Comments:Chromatography was carried out on an Agilent 7890A gas chromatograph using the manufacturer's software (Chemstation) and a HP-5MS gas chromatography column (Agilent Technologies, Santa Clara, CA; 30 m x 0.25 mm x 0.25 m film thickness). The sample injection mode was splitless, and 1 L of each sample was injected. The injection port temperature was held at 250 C throughout the analysis. The GC oven was held at 60 C for 1 min after injection, and the temperature was then increased to 325 C by 10 C/min, followed by a 5 min hold at 325 C. The helium gas flow rates for each Experiment were determined by the Agilent Retention Time Locking function based on analysis of deuterated myristic acid and were in the range of 0.450.5 mL/min.

Instrument Type:Single quadrupole
MS Type:EI
MS Comments:An Agilent GC 7890A coupled with a single quadrupole MSD 5975C (Agilent Technologies, Inc.; Santa Clara, CA, USA) was used, and the samples were blocked and analyzed in random order for each experiment. Data were collected over the mass range 50-550 m/z. A mixture of FAMEs (C8-C28) was analyzed once per day together with the samples for retention index alignment purposes during subsequent data analysis.
