Collection:

Collection ID:CO001162
Collection Summary:Skeletal muscle (BF, LDE) was surgically biosied and flash frozen in liquid nitrogen.
Sample Type:Muscle

Treatment:

Treatment ID:TR001182
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 20-25 s and placed on dry ice/stored at - 80C

Sample Preparation:

Sampleprep ID:SP001175
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:CH001289
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 (part 122-5512), 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.
