FXIIa titration of human plasma (Lot I, see Section 2) relating coagulation time to concentration of exogenous FXIIa concentration expressed in plasma-equivalent-units-per-milliliter (PEU/ml). Dashed line drawn through data is a guide to the eye showing that plasma coagulation time is exquisitely sensitive to FXIIa. Inset plots data as a lin-log calibration curve used to deduce FXIIa concentrations in neat-buffer solutions used in autoactivation experiments. Solid line through the inset data results from linear-least-squares regression through the data interval shown.
