Table 2.

αFXIIa reduction amounts (Δ[FXIIa]) and activity inhibition rate of αFXIIa by FXII contact activation products. (Δ[FXIIa] = [FXIIa]_dose – ([FXIIa]_apparent - [FXIIa]_material), Inhibition rate = $\frac{\Delta [FXIIa]}{[FXIIa]dose}\times 100\%$ , where [FXIIa]_apparent is the activity of the mixed solution with αFXIIa, and [FXIIa]_material is the activity of FXII contact activated solution before addition of αFXIIa.)
