Targeted (Null/Knockout) | Ifng | interferon gamma |
Mice homozygous for the Ifngtm1Ts targeted mutation are viable and fertile. This Ifng -deficient mutant develops type 1 diabetes at the same rate as the NOD/ShiLt parental strain. Specific pathogen free (SPF) conditions are critical as these mice have diminished immune responses to pathogens.
The mutation originally generated on a B6,129 background by Dr. Timothy Stewart (strain 002287) was congenically transferred to the NOD/Lt background using a marker assisted protocol and fixed to homozygosity at backcross generation N7 by Dr. David Serreze, The Jackson Laboratory, Bar Harbor. A genome scan confirmed the stock to be homozygous for linkage markers delineating twenty-three previously identified, insulin dependent diabetes susceptibility loci of NOD/Lt origin.

When maintaining a live colony, homozygous mice may be bred together. Specific pathogen free (SPF) conditions are critical as these mice have diminished immune responses to pathogens.
When using the NOD.IFNnull mouse strain in a publication, please cite the originating article(s) and include JAX stock #002575 in your Materials and Methods section.

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.
