Sample Preparation:

Sampleprep ID:	SP002552
Sampleprep Summary:	Lipids were extracted from 100uL of brain homogenate using a two-phase methyl-tert-butyl ether (MTBE)/methanol/water protocol as described by Matyash et al. (2008), with the addition of the following internal standards: 2000 pmoles SM(d18:1_12:0), 2000 pmoles GluCer(d18:1_12:0), 500 pmoles LacCer(d18:1_12:0), 500 pmoles ST(18:1_17:0), 500 pmoles Cer(18:1/17:0), 200 pmoles C17:0 Sph, 200 pmoles C17:1 S1P, 200 pmoles d3-C16 AcCa, 500 pmoles C17:1 LPE, 500 pmoles C17:1 LPS, 200 pmoles C17:0 LPA, 500 pmoles C17:0 LPC, 5000 pmoles PC(19:0_19:0), 2000 pmoles PS(17:0_17:0), 2000 pmoles C17:0 PE, 2000 pmoles C17:0 PG, 1000 pmoles C17:0 PA, 1000 pmoles d7-18:1_15:0 PI, 2000 pmoles CL(14:0_14:0_14:0_14:0), 2000 pmoles TAG(17:0_17:0_17:0), 500 pmoles DAG d7- 18:1/15:0), 500 pmoles d7- 18:1 MAG, 2000 pmoles C17:0 CholE, 1000 pmoles d7 Chol. Lipids were reconstituted in 400uL of 100% HPLC methanol, then diluted 1/5 in 80% v/v HPLC methanol, containing 1 mM ammonium formate and 0.2% formic acid.
