Sample Preparation:

Sampleprep ID:	SP001068
Sampleprep Summary:	large scale profiling of rat cortex and hippocampus brian tissue. The brain tissue and CSF will be collected for mass spectrometry. To prepare samples, proteins will be removed from collected dialysates by adding cold methanol:water (8:1, v/v) mixture containing 5.0 μg internal standard (IS), myristic-d27 acid, at ambient temperature. Samples will be vortexed for 1 min, incubated on ice for 15 min, and then centrifuged. The supernatant will be completely dried in a SpeedVac, and the lyophilized sample will be subsequently methoxiaminated using 20 μl of a 20 mg/ml solution of methoxyamine hydrochloride in pyridine at 30°C for 90 min and derivatized using 80 μL of N-methyl-N-trimethylsilyltrifluoroacetamide with 1% trimethylchloro-silane (MSTFA + 1% TMCS, Pierce) at 37°C for 30 min.
