Serotonin (5HT) contents of platelet and platelet-poor plasma (PPP) in hypertensive and normotensive states. Using a competitive ELISA technique, platelet and PPP 5HT concentrations from 16 subjects with hypertension were measured and compared with the values from normotension following the manufacturer’s instructions. Samples were read at 405 nm on an ELISA plate reader. 5HT amounts were quantified using standards supplied by the manufacturer, and analyzed using Origin software. The (*) represents the results of a two-tailed Student’s t-test with p < 0.001 (compared with normotensive subjects).
