Study IDST000164
Study TitleMetabolomic analysis of normal and diabetic mouse bone marrow under PBS or metformin treatment
Study TypeUntargeted Metabolomics
Study SummaryWild type and diabetic (MKR) mice were treated daily with intraperitoneal injections of 50 microliters of PBS (control) or metformin (200 mg/kg body weight) for 14 days. Their bone marrow cells were collected and compared by untargeted metabolomics.

Sample Preparation:

Sampleprep ID:SP000183
Sampleprep Summary:Frozen cells were mixed with dry ice-cool 80% methanol (mass-spec grade) at a ratio of 30 ?L/million cells, and then quickly thawed on heat block set at 50 °C for 5 min. The suspension was then processed by three rounds of 1 min vortex at max speed, chilled briefly on dry ice. The mixture was incubated at 4°C for 1 hour before centrifuge at 20,000 x g for 20 min at 4 °C. The supernatant was stored at -20 °C and used as metabolite extract for LC-MS analysis.
