Variable	Washed platelets
	ADP (10 μmol/L; n = 3)∗		Col (2 μg/mL; n = 5)		AA (0.5 mmol/L; n = 5)
	WT	Fut−/−	WT	Fut−/−	WT	Fut−/−
LT (seconds)	14.0 ± 2.1	14.0 ± 2.5	95.2 ± 7.7	110 ± 11.3	35.0 ± 0.8	36.6 ± 1.1
Slope	67.7 ± 3.4	70.0 ± 2.5	59.0 ± 1.8	58.7 ± 1.5	71.1 ± 5.6	67.4 ± 1.5
MA (%)	77.7 ± 0.7	82.3 ± 3.3	81.8 ± 1.2	84.4 ± 0.5	73.5 ± 6.2	74.8 ± 1.3

All values represent means ± SD.

AA, arachidonic acid; Col, collagen; LT, lag time; MA, maximum amplitude.

^∗Human fibrinogen (15 μg/mL final concentration) was added for ADP-stimulated washed platelet aggregation.
