The assay was conducted in Tris-
HCl buffer (50 mM, pH 7.4), containing 0.154 mM sodium
chloride. The same buffer was used for solution preparation of
fibrinogen (w/v 0.1%) and thrombin (10 U/mL). An aliquot of40 μL peptide or Tris-HCl buffer and 140 μL fibrinogen were
added into the plate wells, mixed, and incubated for 10 min. Then
10 μL thrombin was added to start the reaction. All solutions were
mixed vigorously at 37 ◦C for 8 s. The absorbance was measured
in the microplate reader at 405 nm
