Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Transgenic Mating System +/+ sibling x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Richard Lang, Cincinnati Children's Hospital Generation N6+N4F1 (12-MAY-08) Strain Description
These transgenic mice have a diphtheria toxin (DT) inducible system that transiently depletes macrophages. The transgene insert contains a fusion product involving simian diphtheria toxin receptor and green fluorescent protein under the control of the human ITGAM (integrin alpha M) promoter (CD11b). RT-PCR analysis of bone marrow macrophages detects specific transgene expression. Cytological analysis of thioglycollate treated peritoneal cells shows the absence of macrophages. Intraperitoneal injection of DT ablates monocyte/macrophage cells in the peritoneal cavity. Mice that are homozygous for the transgene are viable, normal in size and do not display any gross physical or behavioral abnormalities. Transgene expression is not sufficient to be detected by FACS analysis. 12 hours following DT administration all macrophages are ablated in the peritoneum, kidney and ovary. Macrophage population is restored by day 4 following a single intraperitoneal dose of DT. Administration of DT does not affect polymorphonuclear cells. Higher doses (greater than 25ng/g body weight) of DT sickens the mice. This mutant mouse strain may be useful in studies of the specific role of macrophages in the immune response.In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
Strain Development
A transgenic construct containing sequence encoding DTR/GFP under the control of the human ITGAM (integrin alpha M) promoter was introduced into fertilized FVB/N donor eggs. Founder line 34 was subsequently established. The mice were backcrossed onto C57BL/6 for 6 generations (January 2006).

| Mutation Made By | Richard Lang, Cincinnati Children's Hospital | ||
| Strain of Origin | FVB/N | ||
| Site of Expression | Induced in monocytes/macrophages (fluorescence not sufficient for FACS); transient diptheria toxin (DT)-induced ablation of cells. | ||
| Expressed Gene | DTR, Simian Diphtheria Toxin Receptor, | ||
| 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. | |||
| Promoter | ITGAM, integrin, alpha M (complement component 3 receptor 3 subunit), human | ||
| Molecular Note | The transgene contains a fusion product involving simian diphtheria toxin receptor and green fluorescent protein under the control of the human ITGAM (integrin alpha M) promoter (CD11b), and human growth hormone sequence. Mice carrying this transgene have a diphtheria toxin (DT) inducible system that transiently depletes macrophages. RT-PCR analysis of bone marrow macrophages detects specific transgene expression.

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 ~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 48 hours of 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
