Collection:

Collection ID:CO001814
Collection Summary:Immortalized rat astrocytes (CRL-2005)
Sample Type:Fibroblasts

Treatment:

Treatment ID:TR001834
Treatment Summary:high-glucose DMEM (Gibco) containing 10% FBS and 1% penicillin/streptomycin (Gibco). Isotopic labeling was achieved through 30 min treatments with media containing 4.5 g/L U-13C-glucose (100% of the total glucose content; Cambridge Isotopes); parallel cultures were treated with 4.5 g/L natural-abundance glucose. Simultaneous to the introduction of the labeled substrate, subsets of both unlabeled and labeled cultures were treated with LPS (added to culture media to a final concentration of 1 μg/mL) for the duration of the labeling protocol.

Sample Preparation:

Sampleprep ID:SP001827
Sampleprep Summary:Cells were then washed with phosphate buffer solution and high-performance liquid chromatography (HPLC)-grade water, quenched with 1 mL cold HPLC-grade methanol, scraped from the plate, and pelleted. Pellets were dried on a SpeedVac and subsequently lyophilized. Dried samples were weighed out and extracted with the solvent volumes adjusted to maintain a ratio of 1 mL of solvent per 1 mg of dried cellular material. The final volume of reconstitution solvent was adjusted to 100 μL per 1 mg of dried material. All cell-culture conditions (unlabeled versus labeled, control versus LPSstimulated) were sampled in triplicate.
