Collection:
| Collection ID: | CO003018 |
| Collection Summary: | One million cells from culture were collected via centrifugation for 20 seconds at 18,000xG, washed with 0.9% NaCl, and collected via centrifugation for 20 seconds at 18,000xG |
| Sample Type: | Cultured cells |
Treatment:
| Treatment ID: | TR003034 |
| Treatment Summary: | MEL cells were cultured for up to 8 days in 100 nM folic acid containing RPMI media. The treatments were setup as a reverse time-course experiment and harvested on the same day. Day 0 samples were cultured for 8 days in 2,000 nM folic acid. |
Sample Preparation:
| Sampleprep ID: | SP003031 |
| Sampleprep Summary: | Pellet was resuspended in extraction buffer (80% Methanol, 25 mM Ammonium Acetate and 2.5 mM Na-Ascorbate prepared in LC-MS water, supplemented with isotopically-labelled amino acid standards [Cambridge Isotope Laboratories, MSK-A2-1.2], aminopterin, and reduced glutathione standard [Cambridge Isotope Laboratories, CNLM-6245-10]). Samples were vortexed for 10 sec, then centrifuged for 10 minutes at 18,000 g to pellet cell debris. The supernatant was divided into two tubes and dried on ice using a liquid nitrogen dryer. One tube of dried sample was used for polar metabolite detection. Dried samples were resuspended in 25 μL water |

Chromatography:
| Chromatography ID: | CH003613 |
| Chromatography Summary: | Sample was injected into a ZIC-pHILIC 150 x 2.1 mm (5 μm particle size) column (EMD Millipore). operated on a Vanquish™ Flex UHPLC Systems (Thermo Fisher Scientific, San Jose, CA, USA). Chromatographic separation was achieved using the following conditions: buffer A was acetonitrile; buffer B was 20 mM ammonium carbonate, 0.1% ammonium hydroxide in water; resulting pH is around 9 without pH adjustment. Gradient conditions we used were: linear gradient from 20% to 80% B; 20–20.5 min: from 80% to 20% B; 20.5–28 min: hold at 20% B at 150 mL/min flow rate. The column oven and autosampler tray were held at 25 °C and 4 °C, respectively. |
