Figure 1: The left photo shows the fluorescence intensity of HEK-293 cells which expressed a CFP/DJ-1 protein as control of a FRET experiment. The middle image shows the phase angle derived distribution of fluorescence lifetimes in the range of 0 – 4 ns (imageJ LUT 16 colors, colorbar 0 – 4 ns) which has been masked by an intensity filter. The range of lifetimes around 2 ns was found in all of the 26 cells, which have been measured and showed about 10% FRET efficiency compared to the pure CFP expression. The right image shows the lifetime distribution image weighted by the fluorescence intensity image (the color images are false color coded using the same colorbar and LUT) without mask (courtesy of Prof. Dr. F.S. Wouters and Dr. G. Bunt, University Medicine Göttingen).

Figure 5:The left image shows the fluorescence intensity of a sliced daisy sample (20x air objective). The middle image shows the phase angle derived distribution of fluorescence lifetimes in the range of 0 - 4 ns (imageJ LUT 16 colors, colorbar 0-4 ns). The difference in fluorescence lifetimes clearly allows to differentiate the cells and the pollen grains. The right image shows the lifetime distribution image weighted by the fluorescence intensity image (the color images are false color coded, the modulation frequency was 30 MHz) (courtesy of Prof. Dr. F.S. Wouters and Dr. G. Bunt, University Medicine Göttingen).
