Effect of scuPA/suPAR on plasma fibrinogen concentrations. (A) Four groups of mice (4-5 mice per group) were injected with 11.3 mg/kg scuPA/suPAR complex. (B) Mice (4-5 mice per group) were injected with scuPA alone (11.3 mg/kg) or saline control (Cont.). Two hours later, blood was drawn, plasma was separated, and the fibrinogen concentration was measured. The mean ± SD from 3 animals in each group is shown.
