Collection:

Collection ID:CO001340
Collection Summary:Trypanosoma brucei brucei (T.b.b) bloodstream forms (strain 427) were maintained in vitro in 5-10 ml cultures at 37 °C and 5% CO2 in Creeks minimal media supplemented with 10% HMI-9. The cultures were passaged every 2-3 days and cells were grown to a maximum density of 2x106cells/ml.
Sample Type:Cultured cells

Treatment:

Treatment ID:TR001361
Treatment Summary:For drug-induced metabolic perturbation experiments, cells were sub-cultured at 10e6cells/ml in 20 ml volume with drugs added at 0.5 µM concentration and incubated for a further 5 hours until cell density reached ~2x10e6cells/ml. Cells were then used for metabolite quenching and extraction.

Sample Preparation:

Sampleprep ID:SP001354
Sampleprep Summary:Metabolism was rapidly quenched by rapidly cooling cultures to 4°C in a dry ice and ethanol bath. Cultures were then centrifuged for 10 minutes at 1250g at 4°C. The supernatant was discarded and cells were washed with 1 ml of cold PBS by centrifugation for 1 minute at 2100g at 4°C. The supernatant was removed and cells were extracted with 100 µl extraction solvent containing chloroform: methanol: water (1:3:1 v/v) followed by vortexing at 4 °C for 1 hour. The resulting suspension was centrifuged for 10 minutes at 2100g at 4°C and the supernatant was transferred to glass vials and stored at -80 °C until analysis by liquid chromatography and high-resolution mass spectrometry.
