Collection:
| Collection ID: | CO000924 |
| Collection Summary: | Cardiac (LV) tissue was harvested and immediately flash frozen in a liquid nitrogen cooled biopress. |
| Sample Type: | Muscle |
Treatment:
| Treatment ID: | TR000944 |
| Treatment Summary: | Fraction of cardiac tissue weighed (~25-50 mg wet weight), then the finely cut up tissue quickly added to fresh pre-made buffer (50 % acetyl-nitrile, 50 % water, 0.3% formic acid) at a standard concentration of 25 mg/475 mcl buffer then fully homogenized on ice for ~20 s and placed on dry ice/stored at - 80C. |
Sample Preparation:
| Sampleprep ID: | SP000937 |
| Sampleprep Summary: | The samples were crash deprotonized by methanol precipitation and spiked with D27-deuterated myristic acid (D27-C14:0) as an internal standard for retention-time locking and dried. The trimethylsilyl-D27-C14:0 standard retention time (RT) was set at 16.727 min. Reactive carbonyls were stabilized at 50C with methoxyamine hydrochloride in dry pyridine. Metabolites were made volatile with TMS groups using N-methyl-N-(trimethylsilyl) trifluoroacetamide or MSTFA with catalytic trimethylchlorosilane at 50C. |

Chromatography:
| Chromatography ID: | CH001022 |
| Chromatography Summary: | GC/MS methods follow previous studies using a 6890 N GC connected to a 5975 Inert single quadrupole MS (Agilent Technologies, Santa Clara, CA) (Bonikos et al. 1975; Fiehn 2008; Kind et al. 2009). The two wall-coated, open-tubular GC columns connected in series are both from J&W/Agilent, DB5-MS, 15 meters in length, 0.25 mm in diameter, with an 0.25-l m luminal film. Positive ions generated with conventional electron-ionization at 70 eV are scanned broadly from 600 to 50 m/z in the detector throughout the 45 min cycle time. |
