Figure 2. Intensity profiles of dynamic light scattering (DLS).

Figure 2

Broken line: wild-type Hfq (∼1.0 mg/ml) after incubation at 40°C. Measured at 25°C. Thin line: mixture of wild-type Hfq (∼0.5 mg/ml) and HPII (∼0.5 mg/ml) kept at 4°C. Measured at 5°C. Thick line: the same sample as shown in thin line, but after incubation at 40°C. Measured at 25°C. The horizontal axis is common logarithm scale and the vertical axis is percent of the total intensity. The hydrodynamic diameter of the smaller peak in broken line is 9.8 nm corresponding to a molecular weight of 138 kDa, while that of the peak in thick line is 15.8 nm corresponding to ∼420 kDa.
