Sample Preparation:

Sampleprep ID:	SP000482
Sampleprep Summary:	Cells were homogenized on the MagNA Lyzer, with two 30-sec cycles at 2000 rpm, resting in a -20 °C chilling block for 1 min in between pulses, and centrifuged samples at 16,000 rcf for 4 min. The cell lysate was transferred to a new 2 mL Lo-Bind Eppendorf tubes, with the final cell count approximately 10x10^6 cells for each sample. Of the twenty cell lysate samples, six samples had sufficient volume for study samples and to be included in an analytical quality control (QC) total pool. Aliquots from these cell lysate samples were combined, divided into three total pool aliquots, and processed identically to the cell lysate study samples. All study and pool samples were lyophilized to dryness and reconstituted in a 0.2M phosphate buffer, pH 7.4, in D2O with 10% Chenomx ISTD.
