Collection:
Collection ID: | CO003293 |
Collection Summary: | Blood samples were colected after 12 hours overnight fast and centrifuged 20 min, 3000 RPM, 4ºC |
Sample Type: | Blood (plasma) |
Treatment:
Treatment ID: | TR003309 |
Treatment Summary: | No treatment. Analyses of pre- and post-menopause women with or without depressive symptons |
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). |
