Variation of sedimentation coefficient with rotor velocity.
Ontology highlight
ABSTRACT: The sedimentation coefficients of three proteins, which appeared homogeneous in the ultracentrifuge, have been determined at different rotor velocities. Two of the proteins, ovalbumin and human gamma-globulin, showed sedimentation coefficients that were approx. 10% higher at rotor velocities below 20000rev./min. than at 56100rev./min. The third protein, haemocyanin of Jasus lalandii, could not be investigated over the same rotor-velocity range, but it showed a similar effect.
