Figure 1. Sedimentation velocity analyses for the five collagen peptides.

Figure 1.

Sedimentation boundaries for five collagen peptides (POG)6, (POG)8, (POG)10 and (POG)12 and (POG)10-unblocked were fitted using SEDFIT. Absorbance data were collected at 232 nm at a rotor speed of 60 000 rpm with concentrations of 1.5–2.6 mg/ml. The left panels show the fitted sedimentation boundaries for (POG)6 - (POG)12. The right panels show the individual size-distribution analyses c(s). These analyses produced s20,w peaks at 0.81 S for (POG)6, 0.99 S for (POG)8, 1.06 S for (POG)10, 1.18 S for (POG)10unblocked and 1.06 S for (POG)12. The red line in each panel denotes the theoretical s20,w value for the linear crystal-derived collagen model.
