Ultracentrifugation separates race-mates from enantiomers

摘要

Yitzhak Mastai,Antje Volkel,and Helmut Colfen of Bar-Han University(Israel)and the Max Planck Institute for Colloids and Interfaces(Germany)have used density gradient ultracentrifugation to separate a racemate from excess enan-tiomer crystals.Density gradienttechniques are commonly used to separate mixtures of biopolymers,such as single-and double-stranded DNA,but they had previously not been applied to the separation of chiral compounds.
