| These mice express a tau (MAPT)-sapphire green fluorescent protein (GFP) under the transcriptional control of the mouse neuropeptide Y (Npy) promoter. Fluorescence is observed in distinct neuronal populations of the hypothalamic arcuate nucleus. This strain has been useful in studying the role of neuropeptide Y and leptin in food intake. Hemizygotes are viable and fertile and do not display any gross physical or behavioral abnormalities. | |||||||||||||||

Description
Strain Information
Former Names B6(CBA)-Tg(Npy-MAPT/GFP*)1Rck/J (Changed: 16-MAY-08 ) Type Congenic; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Additional information on Congenic nomenclature. Mating System Noncarrier x Hemizygote (Female x Male) 25-SEP-08 Species laboratory mouse Generation N11+N1F1 (18-DEC-08) Donating Investigator Jeffrey Friedman, Rockefeller University, HHMI Description
These mice express a tau (MAPT)-sapphire green fluorescent protein (GFP) under the transcriptional control of the mouse neuropeptide Y (Npy) promoter. Immunohistochemistry for NPY in colchicine-treated animals demonstrated ~95% colocalization of NPY with the GFP-expressing neurons in the hypothalamic arcuate nucleus. This strain has been useful in studying the role of neuropeptide Y and leptin in food intake. Hemizygotes are viable and fertile and do not display any gross physical or behavioral abnormalities.Development
A transgenic BAC vector carrying Tau (MAPT)-Sapphire GFP in exon 2 of a mouse neuropeptide Y (Npy) gene was introduced to B6CBAF1 embryos. The line was backcrossed ten times to C57BL/6 by the donating laboratory.

| Site of Expression | Fluorescence is observed in distinct neuronal populations of the hypothalamic arcuate nucleus. | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. In some constructs the original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||

Supply Details
| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of approximately nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within two business days following order placement. |

The Jackson Laboratory's Genotype Promise
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.Ordering and Purchasing Information
