Imaging Transgenic Nude Mice Expressing Spectrally-distinct Fluorescent Reporters Emitting From Blue to Far Red Light With One Instrument With Single-nanometer-tuning of Laser-excitation Fluorescence

Using a single instrument, brilliant and well-defined images of GFP, RFP, and CFP mice were obtained with single-nanometer-tuning laser fluorescence excitation. This imaging system will be used in future studies to analyze cancer cells in the colored mice that are spectrally distinct in order to determine how stromal cells and cancer interact in the tumor microenvironment.
