The 1.6 kb core of the E8I Cd8 locus enhancer region was inserted in front of the Cd8a promoter, and iCreERT2 cDNA and an IRES-GFP-polyA cassette were inserted after the promoter to generate the transgene construct. Founder information and line numbers were not available. The pound symbol (#) is used when no line is specified and/or lines are pooled. (J:299786)
