Study TitleInvestigating link between metabolism and circadian rhythm in Drosophila melanogaster
Study SummaryWe are investigating the link between metabolism, circadian rhythm, and a high-fat diet with an emphasis on the role of metabolites that affect protein post translational modifications. We've hypothesized that protein modifications, which are critical to circadian clock functions, can be affected by different metabolic profiles, such as an excess or lack of fat in the diet, that ultimately regulate changes in circadian biology.

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.
