Description
Mice that are homozygous null for the Bcr gene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. No Bcr gene product (mRNA or protein) is detected. Homozygous null animals are more susceptible to lipopolysaccharide (LPS) -induced endotoxemia. Sublethal doses of LPS induce septic shock characterized by a pronounced, sustained neutrophilia and tissue damage to multiple organs. Tissue damage is mediated by neutrophils that exhibit an elevated superoxide production resulting in similarly elevated respiratory burst. Neutrophils obtained from null animals that have been activated in vitro with phorbol myristate actetate (PMA) show an almost 100% increase in respiratory burst over that seen in wildtype neutrophils.

Development
A targeting vector containing a neomycin resistance gene driven by the mouse phosphoglycerate kinase promoter was used to disrupt a portion of intron 1 and exon2 of the Bcr gene. The construct was electroporated into 129S2/SvPas-derived D3 embryonic stem (ES) cells. A herpes simplex virus thymidine kinase was used for negative selection. Correctly targeted ES cells were injected into C57BL/6J blastocysts. The resulting chimeric male animals were backcrossed to C57BL/6J females.

Control Information

  Control
   See control note: The STOCK background of this strain is a mixture of C57BL/6 and 129S2 inbred strains, plus random-bred Black Swiss mice. Thus, the best physiological controls would be wildtype mice from the colony.

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.
