Inhibition of APC and thrombin by PCI in the absence and presence of TM. APC 0.5 nmol/L (A) or thrombin 0.5 nmol/L (B and C) were incubated with 10 (○,•), 25 (□,▪), or 50 (▵,▴) nmol/L PCI, respectively, in the absence (open symbols) or presence (closed symbols) of TM (50 nmol/L rabbit lung [A and B] and 100 nmol/L TM4-6 [C]). At indicated time points, the chromogenic substrates S2366 (1 mmol/L f.c.) or Spectrozyme TH (0.25 mmol/L f.c.) were added to monitor the remaining activity of APC and thrombin, respectively. Please note the difference in x-axis scales in A, B, and C.
