Abstract: In this work we report on the interaction of KLVFF-PEG with fibrinogen (Fbg) in neutral aqueous solutions at 20 °C, for particular ratios of KLVFF-PEG to Fbg concentration, Δ = cKLVFF-PEG/cFbg. Our results show the formation of Fbg/KLVFF-PEG complexes for Δ > 0, such that there is not an extended network of complexes throughout the solution. In addition, cleaved protein and Fbg dimers are identified in the solution for Δ ≥ 0. There is a dramatic change in the tertiary structure of the Fbg upon KLVFF-PEG binding, although the KLVFF-PEG binds to the Fbg without affecting the secondary structure elements of the glycoprotein.
