Table 2.

Platelet-derived microparticle (PMP) and P-selectin-positive platelet (plt:P-selectin) levels measured by A23187 in whole blood and washed platelet suspensions

Sample plt:P-selectin PMP (/104 platelets)
Washed platelet suspension 35·8 ± 7·3 (%) 1320 ± 215
Whole blood 32·4 ± 6·6 (%) 1195 ± 227
P < 0·001 P < 0·05

Data are shown as the mean ± s.d. (n = 5). P values compare the levels of plt:P-selectin or PMPs between whole blood and washed platelet suspensions.
