<p align="justify">Because of the low but distinct fluorescence of wild type spores, we measured and compared the fluorescence intensity of 100 spores per construct (see [https://2012.igem.org/Team:LMU-Munich/Data/gfp_spore data]). We obtained significant differences between wild type spores and all of our '''Sporo'''beads (see [https://2012.igem.org/Team:LMU-Munich/Data/gfp_spore data]). The intensity bar charts in Fig. 6 show the fluorescence intensity, while the 3D graphs illustrate the distribution of fluorescence intensity across the spore surface. This correlates with the localization of our fusion proteins in the crust. For image analysis we measured the fluorescence intensity of an area of 750 pixel per spore by using ImageJ and evaluated the results with the statistical software R.
