The transgene contains a fusion product involving simian diphtheria toxin receptor and green fluorescent protein under the control of the mouse Itgax promoter (CD11c). Two lines were created (line 11 and line 57) with 1 to 2 copies and 20 copies of the transgene, respectively. All CD8+ and CD8- dendritic cells in the spleen fluoresce and are DT sensitive. Immunohistochemical and flow cytometric analyses show that expression of the transgene is specific to splenic dendritic cells. Line 57 inserted into the gene at 80448681-80455738 (Build GRCm38/mm10) resulting in a 7057 bp deletion. Founder line 57 has a copy number of greater than 20.
