These floxed mutant mice possess loxP sites that flank promoter and exon 1 sequences of the Srf gene. This strain may be useful for generating conditional mutations in applications related to studies of cardiovascular disease.

These mice possess loxP sites that flank promoter and exon 1 sequences. Mice that are homozygous for this allele are viable and fertile. When used in conjunction with a Cre recombinase-expressing strain, this strain is useful in generating tissue-specific mutants of the floxed allele. Excision of the floxed fragment results in the removal of key regulatory elements and many of the DNA-binding and dimerization residues of the gene.
When bred to a strain expressing Cre recombinase under the control of mouse transgelin promoter (see Stock No. 004746 for example), this mutant mouse strain may be useful in studies of cardiovascular disease.
loxP sites were inserted 1.4 kb upstream and 1.1 kb downstream of the transcription start site, resulting in floxed promoter and exon 1 sequences. The construct was electroporated into 129/Sv-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. Chimeric animals were crossed with C57BL/6.

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.
