33 Gradient Appendix - RIT - People
142 Appendix VIII ultracentrifugation ultracentrifugation , the characterization of macromolecules by centrifugation at super high speeds, is a foundational technique that has greatly enhanced our understanding of molecular biology. The rate of settling or sedimentation of macromolecules under high centrifugal force is a function of their size and shape. A macromolecule studied in this manner is usually characterized according to its S value (sedimentation coefficient), named after Theodor Svedberg, a Swedish chemist who received the Nobel Prize for his work on colloids and his invention of the ultracentrifuge. The relationship between rate of sedimentation and centrifugal force is: S = velocity/centrifugal force where centrifugal force is r x 2 r = radial distance from the axis of rotation and = angular velocity in radians per second.
