Enantiomeric separations using bovine serum albumin immobilized on ion-exchange stationary phases.

Bovine serum albumin (BSA) can be readily immobilized on ion-exchange stationary phases by frontal analysis of a proper solution. This provides a simple means of adjusting the amount of BSA contained in the column and of measuring it accurately. Although the immobilization is ionic and not covalent, the columns are stable for extensive periods of time. If needed, they can be easily regenerated by the same frontal analysis procedure.
