The present invention relates to methods for preparing an animal tissue for fluorescence microscopy, to an animal tissue obtainable by said methods, to methods for analyzing said animal tissues, and to methods for the detection of metastases, for analyzing the biodistribution of a biopharmaceutical drug, and for analyzing the biodistribution of nanoparticles. The methods for preparing an animal tissue according to the present invention encompass whole-body labeling, clearing and imaging methods. The methods of the invention are advantageous in that they, for instance, allow the visualization of single cells within mammalian tissues including pig and human brains, tumor metastases at the single cell level and of the distribution of biopharmaceutical drugs (e.g. the distribution of cancer-targeting therapeutic antibodies in whole animals such as intact mice) at single cell level in whole mouse. |
