Figure 6
The smearing effect observed in apoferritin. (a) Scattering profile of apoferitin 11 mg ml−1 solution. No mask (solid line), 15 mm-diameter mask (dotted line), 30 mm-diameter mask (chain-dotted line), and measured by PSPC (open circle). The valleys of the scattering are shown by arrows. (b) The charge effect characterized by changing collection time: 3 s (solid line), 2 s (broken line) and 1 s (dotted line). All profiles were taken with an aperture of 4. |
