Where indicated, purified human FXI (Haematologic Technologies, various concentrations) was included.
  • Clot lysis assay Addition of FVIIa results in a dose-dependent prolongation of the clot lysis time (Fig. 1). This effect was optimal at 10 nM FVIIa.

  • Addition of FXI (30 nM) did not alter MCF but prolonged the half-clot lysis time to 16.1 min (Fig. 3).
  • addition of FVIIa (1 nM) resulted in clot protection from t-PA- mediated fibrinolysis (half-clot lysis time; 16.7 min) without any effect on MCF (Fig. 3).
  • FVIIa (1 nM) together with FXI (30 nM) increases the MCF (29 mm), as well as the half-clot lysis time (24.2 min, Fig. 3).
  • Clot assay Aliquots (55 ⁇ l) of rFVIIa (1 ⁇ g/ml) alone, FXI (25 nM) alone, or rFVIIa and FXI in 50 mM Pipes, 100 mM NaCl, 2 mM EDTA, 1 % BSA, pH 7.2, were incubated for 5 min with a 55 ⁇ l aliquot containing 100 ⁇ M PC/PS vesicles and 50 mM CaCl2 in the same buffer. A 55 ⁇ l aliquot of normal human plasma (NHP) was then added and clotting followed for 400 seconds in an ACL clotting machine using the standard APTT program.
  • NHS normal human plasma
  • Clot assay Prior to addition of rFVIIa or FXI, NHP did not clot within the 400 seconds monitoring time. Following addition of FXI (25 nM) the clotting time was still longer than 400 s. Addition of FVIIa (1 ⁇ g/ml) reduced the clot time to 159.4 ⁇ 1.4 seconds (Fig 4). Addition of both FVIIa (1 ⁇ g/ml) and FXI (25 nM) reduced the clot time to 95.0 ⁇ 1.4 seconds (Fig 4).
