Figure 1 F.IX activation by F.XIa and by the tissue factor:factor VIIa (TF:F.VIIa) complex.

Figure 1 F.IX activation by F.XIa and by the tissue factor:factor VIIa (TF:F.VIIa) complex.

F.IX (400 nM) was incubated with 10C12 (filled symbols) or a control antibody (NTN: anti-neurturin) (open symbols) in HBSA-5 mM CaCl₂. (A) 1 nM F.XIa was added to start the reaction. (B) Relipidated TF:F.VIIa (4 nM:1 nM) (circles) or membraneTF:F.VIIa (150 μg/ml:1nM) (squares) was added to start the reaction. At defined time intervals reaction aliquots were quenched in EDTAethyleneglycol and F.IXa amidolytic activity in each sample was determined after adding F.IXa substrate #299. The inhibition of the rates of F.IXa generation were expressed as fractional rates (vᵢ/vo) ± SD of 4 independent experiments (except for the NTN control in Fig. 1A where n = 3)

10C12 was diluted in citrated plasma of guinea pig and rat. After an incubation of 10 min, human relipidated tissue factor (Innovin) or Actin FS were added to start the PT (open symbols) and APTT (filled symbols) reaction, respectively. The effects on clotting were expressed as fold prolongation of control plasma clotting times. Diamonds = guinea pig; circles = rat.

10C12 and controls were given by intravenous bolus administration 15 min prior to the initiation of CFVs in the carotid artery. The number of CFVs during a 40 min period was recorded and the thrombosis index calculated as the ratio of CFVs divided by the number of applied pinches. ** p<0.01, *** p <0.001 versus control by Mann-Whitney U-test following determination of significant differences between multiple groups in KruskalWallis test

The treatment groups were saline (open bar), 10C12 administered as a single bolus of 30 μg/kg (hatched bar), and heparin administered as a bolus of 100 U/kg followed by a continuous infusion of 1 U · kg⁻¹ · min⁻¹ for 30 minutes (closed bar). N5 per treatment. Times were 0 to 30 minutes (before treatment), 30 to 60 minutes (post-treatment but during the heparin infusion), 60 to 90 minutes (post-treatment but after termination of heparin infusion). *P≤0.05 versus saline control.
