Clotting activities of fX derivatives in PT and APTT assays. (A) The clotting activities of fX derivatives wild type (open circles), R71A (filled circles), E74A (open squares), E76A (filled squares), and E77A (open triangles) at four different dilutions (0.05–0.4 μg/mL) were determined by a PT assay as described in Materials and Methods. (B) The clotting activities of the same fX derivatives (the same symbols) at four different dilutions (0.2–1.6 μg/mL) were determined by an APTT assay as described in Materials and Methods.
