FALP was purified in parallel from approximately 32 mL of fresh serum (sFALP) or plasma (pFALP), as described in “Methods” and reconstituted in approximately 0.2 mL of PBS. The LBP and fibrinogen concentrations of the FALP preparations were measured by ELISA as described in Materials and Methods.

Data are the average and the standard errors from three measurements.

Expressed as the concentration of full-length fibrinogen. The experiment was performed twice with similar results.
