FIGURE 1.

Time course (350 s (A) and 50 s (B)) of the PSF aggregation during Fe²⁺ oxidation. Aggregation was initiated by mixing apoPSF and Fe²⁺ aerobically, and association was followed by the intensity of scattered light at a 90° to the incident beam. The curve represents an average of six experimental measurements. Conditions: [apoPSF] = 0.5 μm in 100 mm Mops (pH 7.0), 24–84 μm FeSO₄, 25 °C.
