Project ID:PR000353
Project DOI:doi: 10.21228/M8DW3Q
Project Title:Metabolomics of Mice Cohousing and Microbiota Transfer
Project Summary:Metabolomics analysis was performed on twelve mice serum samples from Dr. Martin Blaser's laboratory at NYU school of medicine. Serum from week 15 mice were analyzed: (a) mice received low-dose antibiotics until week 4 (STAT), (b) mice received no antibiotics (control), (c) mice received low dose antibiotics (STAT) and then cohoused with control animals (STAT-coho), (d) mice received no antibiotics and then were cohoused with STAT animals (Control-coho). In this collaboration, we are interested in the metabolic differences among these groups.

Sample Preparation:

Sampleprep ID:SP000931
Sampleprep Summary:Extraction, Solvent Removal, Resuspension, Solvent Removal, Two-step Derivatization and Addition of FAME Markers
Processing Method:30 µL of serum were added to Eppendorf tube. Add 1000 µL of 3:3:2 ACN:ISP:H20 extraction solution to aliquots, shake and centrifuge for 2 minutes at 4C and 14000 rcf to precipitate proteins. Sample was split into (2)-450 µL fractions, one fraction was archived in -80°C the second fraction was subject t complete sample processing. Transfer supernatant to a new vial. Evaporate supernatant to complete dryness at room temp.
Processing Storage Conditions:On Ice and or 4⁰C cold room
Extraction Method:(step 1) 3:3:2 Acetonitrile:Isopropanol:H2O, (step 2) 1:1 Acetonitrile:H2O
Extract Storage:-80⁰C
Sample Resuspension:Samples resuspended in 200 µL of 1:1 ACN:H2O. Evaporated to dryness w/speed vac.
Sample Derivatization:Formation of methoximes by adding 10µL of 40mg/mL MeOx in pyridine to each sample. Placed onto Thermomixer for 90 min at 30⁰C. Then FAME retention index markers and MSTFA added to each sample for derivatization step. Samples returned to Thermomixer for 45 min at 70⁰C.
Sample Spiking:Fatty acid methyl esters (FAME)
