Patent ID: 10851360

Abstract:
In one embodiment, the invention provides a method of purifying recombinant alpha-galactosidase A. The method includes obtaining a lysate from cells recombinantly expressing alpha-galactosidase A grown in a cell culture medium having non-precipitating phosphate; contacting said lysate with a first chromatography media that binds α-D-mannopyranosyl or α-D-glucopyranosyl; eluting alpha-galactosidase A from the first chromatography media to generate a first eluate having alpha-galactosidase A, wherein said eluting includes at least one elution pause between 4 and 16 hours; contacting the first eluate with a second chromatography media that binds galactose binding proteins; and eluting alpha-galactosidase A from said second chromatography media to generate a second eluate containing said recombinant alpha-galactosidase A.
