Collection:

Collection ID:CO001149
Collection Summary:After each subject completed the treatment for the required time, the head of the fly was removed from the body over dry ice. Each portion of tissue was placed in a 1.5 mL tube and stored at -80°C until shipped to the WCMC for analysis.
Sample Type:Tissue
Volumeoramount Collected:Variable, depending on the size of the fly.
Storage Conditions:-80℃

Treatment:

Treatment ID:TR001169
Treatment Summary:48 flies were split into two treatment groups, with 24 flies in each group. Group 1 consisted of a High Fat Diet (HFD, Cornmeal diet + 15% coconut oil) and Group 2 consisted of a Non-Fat Diet (NFD, Cornmeal). Within each group, flies were placed in one of four smaller groups, depending on how long they would be on either the HFD or NFD. These groups are ZT4, ZT10, ZT16, ZT22. Each of these smaller groups consisted of 6 flies, to create 4 groups of 6 flies each in both of the diet treatments.

Sample Preparation:

Sampleprep ID:SP001162
Sampleprep Summary:Add 1 mL of 3:3:2 Acetonitrile:Isopropyl Alcohol:LC-MS Grade Water to each preweighed sample. Vortex each sample for 5 seconds. Shake at 4°C for 5 minutes using the Orbital Mixing Chilling/Heating Plate. Keep remaining samples on ice before shaking. Centrifuge samples for 2 minutes at 14000 rcf. Aliquot two 450 µL portions of the supernatant. Submit one to analysis and save one as backup at -20°C. To the submitted sample, dry in Labconco Centrivap. Submit to derivatization.
Sampleprep Protocol Filename:SOP_blood-GCTOF-11082012_332.pdf
Sampleprep Protocol Comments:Extraction solvent is prepared previously. Begin procedure at Sample Preparation under step 3.
Sample Derivatization:Add 10 µL of prepared MeOX solution to each sample. Shake for 1.5 hours at 30°C. Add 91 µL of prepared MSTFA + FAME solution to each sample. Shake for 30 minutes at 37°C.
