Sample Preparation:

Sampleprep ID:	SP003307
Sampleprep Summary:	Aliquots of 50 µL of plasma were added into a 96-deep well plate cell to which 1 µL of thiol-derivatization solution (200 mM N-ethylmaleimide (NEM) + 2 mM citric acid) was added. Subsequently, 200 µL of precipitation solution (acetonitrile/isopropanol (7:3, v/v) + 1% formic acid + isotopically labelled internal standards) were added. After vortex agitation for 10 min. and refrigeration at -20ºC for 10 minutes, the samples were centrifuged (14.000 rpm for 10 minutes at 4°C).
