The relative expression and GAPDH-normalized expression of P2Y₁₂ (a) and P2Y₁ (b) protein correlated with the percentage of P-selectin positive platelets after stimulation with 1 μM of 2MeS-ADP. In (a) there is a significant correlation of P-selectin positive platelets with P2Y₁₂ protein expression, with r²=0.43 (P <0.05) (n =14). In (b) there is no significant correlation of P-selectin positive platelets and P2Y₁ protein expression (r²=0.002, P=0.88, n=14) (pos plts positive platelets)
