Heparin-dependent 14C-serotonin release by KKO.
14C-labeled platelet-rich plasma was incubated with 80 μg/mL KKO (or isotype control, IC) in the presence of hPF4 (10 μg/mL) and subsequently added to wells containing labeled platelets with the indicated concentrations of heparin. The data shown are the mean ± 1 SD of triplicate measurements and are representative of at least 3 independent determinations.
