Thrombin, collagen, U46619, and arachidonic acid-induced aggregation responses are largely unaffected by disruption of the P-12LO gene. Agonist was added to PRP as indicated by the arrow. Extent of aggregation of P-12LO−/− mouse platelets was not significantly different from wild-type control mouse platelets stimulated with γ thrombin (10–100 nM), collagen (2–40 μg/ml), U46619 (0.5–20 μM), or arachidonic acid (20–100 μM) (n = 4 to 6).
