Study ID	ST002432
Study Title	Metabolic impacts of metformin to seasonal influenza vaccination: a pilot study of drug interaction with the immune response
Study Summary	We report here a double-blinded pilot study of seasonal influenza vaccination, where half of the participants received daily metformin administration. Global metabolomics was measured in the plasma samples at six timepoints. Metformin signatures were successfully identified in the metabolomics data. Statistically significant metabolite features were found both for the vaccination effect and for the drug-vaccine interactions.

Sample Preparation:

Sampleprep ID:	SP002527
Sampleprep Summary:	The plasma samples were thawed in ice. Metabolites extraction were carried out by protein precipitation using extraction solvent, acetonitrile:methanol (8:1, v/v) containing 0.1% formic acid and isotope labelled Trimethyl-13C3]-caffeine, [13C5]-L-glutamic acid, [15N2]-Uracil, [15N,13C5]-L-methionine, [13C6]-D-glucose and [15N]-L-tyrosin as spike-in controls. 30 μl of plasma was taken and 60 μl of extraction solvent was added. All samples were vortexed and incubated with shaking at 1000 rpm for 10 min at 4°C followed by centrifugation at 4°C for 15 min at 15,000 rpm. The supernatant was transferred into mass spec vials and 2 μl injected into UHPLC-MS.
