The Free-Running-Type Equilibrium Ultracentrifuge

Shaptsr 5 Sedimentation equilibrium in the analytical ultracentrifuge

For many years analytical ultracentrifugation was the major source of information on the heterogeneity and molecular size of macromolecules. In the field of protein chemistry the question of solute heterogeneity is now usually addressed by gel electrophoretic and gel chromatographic techniques, and the molecular wetght is either calculated from the amino acid sequence or obtained by mass sPectr...
