Sample Preparation:

Sampleprep ID:	SP000911
Sampleprep Summary:	A total of 200 serum samples and 2 CHEAR Serum Reference Material aliquots were thawed on ice for sample preparation, 150 uL of the thawed serum sample were transferred to labeled tubes on ice where they were mixed with 100 uL of NMR 0.9% Saline Solution containing 2.5 mM formate. Samples were randomly assigned to one of two pools, either Pool 1 or Pool 2. An aliquot of 15 uL of each study sample was added to create their corresponding pools. A 150 uL aliquot was taken from each pool to make 10 aliqouts. Another nine pools from the CHEAR reference material samples were aliquoted and processed along with the study samples and study pools. Pool aliquots were processed identically to the study samples, as described above. Sample tubes were vortexed for 4 minutes on a multi-tube vortexer and centrifuged at 16,000 rcf for 4 mininutes. A volume of 250 uL was taken from each sample supernatant and transferred into a pre-labeled 3mm NMR tube for data acquisition on a 600 MHz spectrometer.
