Sampleprep Summary: | 1. Weigh 4 mg tissue sample ( muscle 20 mg) in to a 2.0 ml eppendorf tube. Add 1.0 mL extraction solvent to the tissue sample and using GenoGrinder homogenize samples for 45 seconds ensuring that sample resembles a powder. 2. Centrifuge the samples at 2500 rpm. for 5 minutes. Aliquot 2 X 500µl supernatant, one for analysis and one for a backup sample. Store backup aliquot in the -20°C freezer. 3. Evaporate one 500µl aliquot of the sample in the Labconco Centrivap cold trap concentrator to complete dryness 4. The dried aliquot is then re-suspended with 500l 50% acetonitrile (degassed as given) (only for liver and brain samples). 5. Centrifuge for 2 min at 14000 rcf using the centrifuge Eppendorf 5415. 6. Remove supernatant to a new Eppendorff tube. 7. Evaporate the supernatant to dryness in the the Labconco Centrivap cold trap concentrator. 8. Submit to derivatization. |
