Fig. 5. Three-dimensional 2-photon confocal laser scanning microscopy (2P-CLSM) of
PHD1, PHD2, PHD3 and FIH-1. Different EGFP fluorescence intensities of single
cells are visualized in false colors as indicated by the color bar. Up to 64
optical slices through transfected cells were recovered by 2P-CLSM. After
reconstruction of the optical slices the distribution of the EGFP fluorescence
within a single cell is 3D-visualized. A cut through the cell reveals the
inside distribution. Overlays of all the optical slices are shown in the
inserts (Metzen et al.,
2003).
