Procedure
Procedure
40m
40m
Gently invert the plasma tubes at 180° and back 8-10 times immediately after collection. Allow Duration00:20:00 - Duration00:30:00 to cool down prior to sample processing.

30m
Centrifuge the green cap tube(s) in at Centrifigation1800 x g, Room temperature, 00:10:00 NO BRAKE.

10m
Centrifigation
After centrifugation there should be a clear separation between the red blood cells at the bottom and the plasma at the top.

Use the Pasteur pipette provided or a micropipette to carefully aliquot Amount500 µL of the plasma from the green cap tube (Lithium Heparin) into the 2-3 x 1ml cryovials (Amount500 µL into each tube) labelled as LH-PLA.

Note
Do not to disturb the red blood cell layer. If the sediment is disturbed the centrifugation step must be repeated.

Place plasma samples in Temperature-80 °C .
