In all subfigures, the abscissa represents the molar ratio of fibrinogen:conjugate. Percent clottable protein was quantified from the remaining protein in solution after clot formation. (A) Non-PEGylated peptides and (B) PEGylated peptides were evaluated; GPSPFPAC (●), GPRPAAC (□), GPRPFPAC (▾), and GPRPPERC (◇).(Mean ± SD; n= 6–9; # denotes p < 0.05, * denotes p < 0.01, and $ denotes p < 0.001).
