Rescue of β-1,4 galactosyltransferase I levels in patient fibroblasts by transient transfection with HA-COG1 cDNA. Double-immunofluorescent staining for HA-Cog1 and β-1,4 galactosyltransferase I in patient fibroblasts transiently transfected with an expression vector encoding Cog1 with an HA tag at the C terminus for two independent transfections. (Upper) Intermediate expression of the HA-Cog1; (Lower) high overexpression. All cells overexpressing HA-Cog1 (arrows) displayed an increase in immunostaining for β-1,4 galactosyltransferase.
