Abstract
A method for the recovery of refined .alpha.-galactosidase is disclosed. This method comprises the steps of bringing an .alpha.-galactosidase-containing liquid into contact with a weakly acidic cation-exchange resin in the presence of a buffer solution for thereby allowing .alpha.-galactosidase to be selectively adsorbed by said resin, desorbing the adsorbed .alpha.-galactosidase from said resin by use of a buffer solution of a type such that at least one of the two factors, concentration and pH, has a higher value than that of the buffer solution used in said adsorption and thereafter recovering the desorbed .alpha.-galactosidase.
