Tg(Foxp3-HBEGF/EGFP)23.2Spar

The RP23-267C15 bacterial artificial chromosome (BAC) containing at least ten mouse genes was obtained. This BAC was modified by targeting a simian diphtheria toxin receptor-enhanced green fluorescent protein (DTR-eGFP) fusion protein and an SV40 polyA element into the first exon of the Foxp3 (forkhead box P3) locus: none of the other loci on the BAC were mutated. Two high expressing lines (16.1 and 23.2) were established. Analysis revealed selective DTR-eGFP expression within the CD4+ T cell compartment, with the highest expression within the CD25+ subset.
