A 50 mW handheld blue laser (447 nm) is now located in the confocal suite. This device excites green fluorescent proteins such as GFP with fluorescent emission of 480-750 nm observed using the Thor Labs LG2 protective glasses. Use the handheld laser to genotype your transgenic organism by eye before dissection/mounting for confocal observation, or use it as a rapid test for fluorescence under a dissecting microscope. See the facility director for more information and uses.
