Progress in Chiral Stationary Phases Based on Proteins and Glycoproteins

Chemical and Pharmaceutical Bulletin, 2022
A lot of chiral stationary phases (CSPs) have been introduced for the purpose of analytical and preparative separations of enantiomers. CSPs based on proteins and glycoproteins have unique properties among those CSPs. This review article deals with the preparation of CSPs based on proteins and glycoproteins, their chiral recognition properties and ...
