Collection:
| Collection ID: | CO002405 |
| Collection Summary: | Worms were washed and pelleted, M9 media was removed with ~100µl remaining in the sample, and the sample was snap frozen. |
| Sample Type: | Worms |
Treatment:
| Treatment ID: | TR002424 |
| Treatment Summary: | Ncl-1 and tif-IA knockdown was achieved by feeding the worms for 2 generations with bacteria (from the Ahringer RNAi feeding library, Source BioScience Ltd.) producing the corresponding dsRNA. Worms were cultured under standard conditions as described in ‘Wormbook’, F1 was grown at 15°C and F2 at 20°C, and F2 animals were grown on RNAi until days 2, 6 or 12 of adulthood. |
Sample Preparation:
| Sampleprep ID: | SP002418 |
| Sampleprep Summary: | Free fatty acids were extracted from C. elegans by successive addition of PBS pH 7.4, methanol, chloroform, and saline to a final ratio of 14:34:35:17. Evaporation of the organic layer yielded a lipid film that was dissolved in methanol and subjected to UPLC-MS/MS. |
| Extract Storage: | -20℃ |
