Figure 6: Localisation of n-frutalin and r-frutalin in HeLa cells by fluorescence confocal microscopy. Representative projections for the cellular localisation of each frutalin form in HeLa cells 1 h after incubation at 37°C are shown: n-frutalin – projection of 38 slices of 50 in the total; r-frutalin—projection of 13 slices of 25 in the total. Legend: (A) nuclear staining with DAPI; (B) lectin staining with FITC; (C) bright field; (D) merged images.
