Pressure-induced dissociation of aggregates of myelin proteolipid protein

Sedimentation velocity and equilibrium experiments have revealed an extremely pressure-sensitive aggregation of myelin proteolipid protein in the presence of Triton X-100, dissociation of the protein aggregate being observed at pressures that are several orders of magnitude lower than those effecting disaggregation of many other proteins. These results highlight the need to employ a range of angular velocities in sedimentation studies of intrinsic membrane protein.
