Sampleprep Summary: | Brain tissue samples were homogenized in 50:50 Acetonitrile:Water (10 µL to every 1 mg of tissue) with washed ceramic beads on a MagNA Lyser, using two 30 sec pulses at 2,000 rpm with a 1 min chilling step in between pulses. Samples were vortexed on a multi-tube vortexer for 2 min at 5,000 rpm and centrifuged at room temperature for 4 min at 16,000 rcf. A 50 µL aliquot of each experimental brain tissue homogenized supernatant was transferred to a labeled 2.0 mL Lo-Bind eppendorf tube. Analytical pooled samples were created by combining 15 µL aliquot from each experimental sample in a 2.0 mL Lo-Bind eppendorf tube. The QC pooled sample was vortexed for 30 sec and 50 µL aliquots were transferred to 5 labeled 2.0 mL Lo-Bind eppendorf tubes. Next, 350 µL of acetonitrile was added to study sample and QC pooled sample tubes. The samples were vortexed on a multi-tube vortexer for 2 min at 5,000 rpm, and centrifuged at room temperature for 4 min at 16,000 rcf. The supernatants were transferred to new labeled tubes and dried on a lyophilizer overnight. Dried samples were reconstituted in 50 µL of 95:5 Water:Methanol, mixed on an analog vortex mixer for 1 min with speed set at 10. Then, the samples were centrifuged at room temperature for 4 min at 16,000 rcf, and the supernatants were transferred to autosampler vials for data acquisition. |
