These mice have the Ple112-EGFP transgene targeted as a single copy "knockin" into the upstream region of the Hprt locus on the X chromosome. The promoter/regulatory regions of the human HCRT gene direct expression of EGFP.

General Note | Germ line transmission of mutant cell line mEMS1736 has been established. |
Molecular Note | The Ple112-EGFP transgene (pEMS1418) was designed with the 1295 bp Ple112 minipromoter (HCRT-B; derived from a subsection of the promoter and an upstream putative regulatory element from the human hypocretin (orexin) neuropeptide precursor (HCRT) gene) upstream of a minimal F5 mutant-frt site, an enhanced green fluorescent protein (with mutated TAA->TTA stop), a nuclear localization signal, a second minimal frt site, an SV40 early polyA signal, and a human HPRT complementary sequence (containing exon1, intron1, exon2, and part of intron2). This construct was targeted as a single copy knockin to the Hprtb-m3 mutant locus on the X chromosome. The promoter/regulatory regions of the human hypocretin (HCRT) gene directs expression of enhanced green fluorescent protein (EGFP) to the hypothalamus. Under the higher magnification, EGFP immunoreactivity can be detected in the cell bodies and processes of hypothalamic neurons. Other (lateral) regions of brain did not display any EGFP-positive cells. |

Facility Barrier Level Descriptions
The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
