Figure 1.
(A) The temperature dependence of the self-assembly process for peptide O14A (7 mg/mL, PBS, pH = 7) monitored by turbidity measurements (absorbance at 313 nm). (B) Turbidity curves showing temperature induced self-assembly of collagen peptides (7 mg/mL, PBS, pH = 7): (1) (POG)10 at 58°C, (2) O14A at 52°C, (3) P13L at 51°C (dashed line), and (4) P13A at 51°C. The inset shows turbidity (absorbance at 313 nm) measured as a function of time at 51°C for the peptide P13L at a higher concentration of ∼16 mg/mL. (C) DSC profile of the thermal unfolding of (POG)10 (○), O14A (■), and P13L (▲).
