Collection:
| Collection ID: | CO003228 |
| Collection Summary: | Animals were euthanized by CO2 inhalation 16 hours following the final injection and transcardially perfused with ice-cold PBS. Whole brains and spinal cords were then excised, flash frozen in liquid N2, and stored at –80°C for biochemical analysis. |
| Sample Type: | Brain |
Treatment:
| Treatment ID: | TR003244 |
| Treatment Summary: | Mice were administered i.p. injections of saline (vehicle) or 4 g/kg 2DG (Cayman Chemical) twice weekly for six weeks. |
Sample Preparation:
| Sampleprep ID: | SP003242 |
| Sampleprep Summary: | Metabolites from equal amounts of frontal cortex tissue were rapidly extracted in 80% ice-cold methanol. Extracted samples were vortexed twice, cleared by centrifugation at 14,000 x g for 20 minutes at 4°C, and stored at -80°C. |

| MS Comments: | 1. A Sequant ZIC-pHILIC column (2.1 mm i.d. × 150 mm, particle size of 5 µm, Millipore Sigma) was used for separation of metabolites. A 2.1 × 20 mm guard column with the same packing material was used for protection of the analytical column. Flow rate was set at 150 μL/min. Buffers consisted of 100% acetonitrile for mobile phase A, and 100% acetonitrile for mobile phase B. The chromatographic gradient ran from 85% to 30% A in 20 min followed by a wash with 30% A and re-equilibration at 85% A. Column temperature was 30 C. |
