Transgenic (Reporter) |
These HLL transgenic mice serve as a reporter of NF-κB activity and inflammation, by virtue of their expressing NF-κB-driven luciferase. The transgenic construct contains firefly luciferase under the control of the proximal 5’ human immunodeficiency virus (HIV-1) long terminal repeat (LTR), which requires NF-κB activity for transcription.
LPS challenge confirmed luciferase expression reflects NF-κB activation in a temporal, spatial and organ -specific manner. Mice that are hemizygous for the transgene are viable and fertile. The Donating Investigator has not attempted to make this strain homozygous. Differences in expression levels between hemizygotes and homozygotes have not yet been determined (July 2015). During backcrossing, the Y chromosome may not have been fixed to the C57BL/6 genetic background.
A transgenic construct (designed by Dr. Lawrence Kerr in 1995) containing 0.68kb sequence from the proximal HIV-long terminal repeat upstream of the luciferase coding region (in the pGL2-basic plasmid vector)
was injected into fertilized mouse eggs. Founder line 27 was subsequently established on a C57BL/6 and DBA background. The Donating Investigator intercrossed hemizygotes to produce homozygotes. The mice were then backcrossed to C57BL/6 for 10 generations. During backcrossing, the Y chromosome may not have been fixed to the C57BL/6 genetic background. Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6J (Stock No. 000664) at least once to establish the colony.

Molecular Note | The transgenic construct contains a cDNA encoding firefly luciferase under the control of tandem copies of a 36-base enhancer from the 5' HIV-long terminal repeat (containing two NF-kappaB binding sites, GGGACTTTCC) upstream of a HSV (herpes simplex virus) minimal thymidine kinase promoter. |
When maintaining a live colony, hemizygous mice may be bred together, to wildtype siblings, or to C57BL/6J (Stock No. 000664). The Donating Investigator has not attempted to make the strain homozygous.

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.
