Sections "SAMPLEPREP" contain missmatched items: {'SAMPLEPREP_SUMMARY': ['"1. Weigh 4mg tissue sample in to a 2mL Eppendorf tube. 2. Add 1mL extraction solvent to the tissue sample and homogenize for 45 seconds ensuring that sample resembles a powder. In between samples, clean the homogenizer in solutions of methanol, acetone, water, and the extraction solvent in the order listed. 3. Vortex samples for 10 seconds, then 5 minutes on 4°C shaker. 4. Centrifuge the samples for 2 minutes at 14,000 rcf. Aliquot 500μL supernatant for analysis, and 500μL for a backup. Store backup aliquots in the -20°C freezer. 5. Evaporate one 500μl analysis aliquot in the Labconco Centrivap cold trap concentrator to complete dryness (typically overnight). 6. The dried aliquot is then re-suspended with 500l 50% acetonitrile (degassed as given) 7. Centrifuge for 2 minutes at 14,000 rcf using the centrifuge Eppendorf 5415. 8. Remove supernatant to a new Eppendorf tube. 9. Evaporate the supernatant to dryness in the the Labconco Centrivap cold trap concentrator. 10. Submit to derivatization."', '1.
