Collection ID:CO001087
Collection Summary:Blood was collected from rats after completing either the high salt or low salt diet for a number of days. Rats fasted overnight before blood collection. Blood was then processed to submit only the plasma for GC-MS analysis.
Sample Type:Blood (plasma)


Treatment ID:TR001107
Treatment Summary:18 rats were placed into either a high salt diet group (2.0% NaCl) or a low salt diet group (0.3% NaCl), to create 2 groups of 9 rats each. The diet began at day 32 of life and continued for a number of days.

Sample Preparation:

Sampleprep ID:SP001100
Sampleprep Summary:Samples were vortexed for 3 seconds to homogenize. Added 30 µL of each sample to a 1.5 mL eppendorf tube. Added 1 mL of extraction solvent (3:3:2 ACN:IPA:Water). Vortexed for 10 seconds. Shake for 6 minutes at 4°C. Centrifuged for 2 minutes at 14000 rcf. Aliquoted 2 x 475 µL portions of the supernatant into new tubes. Save one aliquote at -20°C for backup and dry the other in a centrivap to complete dryness. After the sample is dry, add 500 µL of 50:50 ACN:IPA. Centifuged for 2 minutes at 14000 rcf. Aliquoted 475 µL of supernatant to a new tube. Evaporate to complete dryness in centrivap. Submit for derivitzation.
