Figure 8.

Kratky plot of successive exposures of a single GI sample under alternating ambient- and high-pressure conditions. The overall lower intensity of the high-pressure profiles (100 and 200 MPa) is consistent with a change in scattering contrast which assumes that the protein is much less compressible than water. After a one-time initial transient intensity decline of 2% in going from ambient to 10 MPa, all ambient profiles overlay. Each profile was collected after waiting 5 min with no exposure to help clear potentially damaged material from the region of the beam.
