Figure 1.

Alpha-galactosidase activity resulting from 1-deoxy-galactonojirimycin administration in transfected COS-7 cells. Four independent experiments performed in duplicate for 1-deoxy-galactonojirimycin (20 micromolar) administration in COS-7 transfections were performed. Values are expressed as percentage of COS-7 cells transfected with wild type. Standard deviations is indicated by bars and differences that are statistically significant are flagged by asterisks (p < 0.05:*; p < 0.01: **; p < 0.005:***; p < 0.001 :****)
