Purification of recombinant GBA from cell-culture medium with purification chromatograms and SDS–PAGE analyses for each purification step. GBA (∼55 kDa) was extracted from the medium by hydrophobic interaction chromatography followed by two rounds of cation-exchange chromatography with the addition of Tween 80 detergent. Purification was completed by a size-exclusion step to remove Tween 80. |
