Invented in 1926, analytical unltracentrifugation (AU) was popular in the 1950s and 1960s for molecular interaction applications, but lost favor due to the lengthy time it took to analyze data from experiments. However, advances in data analysis software, design and technology have spurred an increase in the use of AU.
Analytical ultracentrifuges are stand-alone systems that dwarf the bench-top centrifuges in terms of size and power. The instruments rotate solutions in excess of 60,000 rpm and commonly operate in the 100,000 rpm range. Such high rotational speed induces sedimentation in the sample. AU is used to characterize the solution-state behavior of ...
