Platelet distribution in the plasma phase
To evaluate a potential platelet gradient through the plasma
phase, we investigated the distribution of platelets in the plasma
of a 10 mL collection tube after a 10 min centrifugation at 2000 g.
We found platelets to be equally distributed in the plasma phase of
samples from the 10 volunteers (Fig. 3) except for the last gradient
plasma (gradient D) in two samples which contained a higher
number of platelets.
