An optical isomer separating agent comprises a stationary phase in which the molecular structure of ovomucoid fixed to a carrier is partly modified, or a stationary phase in which ovomucoid having the molecule partly modified is fixed to a carrier is disclosed. A process for producing an optical isomer separating agent comprises the steps of immobilizing ovomucoid on a carrier and modifying the ovomucoid is disclosed. Furthermore a process for producing an optical isomer separating agent comprises the steps of modifying ovomucoid and immobilizing the modified ovomucoid on a carrier is disclosed.

Method of resolving a mixture of optical isomers

Separating agent comprising bonded conalbumin

A separating agent comprising ovomucoid and a carrier is useful to separate an optical isomer from a racemoid by way of chromatography.
