These floxed Slc32a1tm1Lowl (also commonly referred to as Vgatflox/flox) mice possess loxP sites flanking exon 2 of the Slc32a1 (or Vgat) gene. These mice may be useful for studying the physiological effect of GABAergic neurotransmission on the regulation of energy balance.

These Vgatflox/flox mutant mice possess loxP sites flanking exon 2 of the solute carrier family 32 (sodium-dependant inorganic phosphate cotransporter), member 1 (Slc32a1 or Vgat) gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exon 2 deleted in the cre-expressing tissue. These mice may be useful for studying the physiological effect of GABAergic neurotransmission on the regulation of energy balance.
For example, when crossed to a strain expressing Cre recombinase in agouti-related protein (AgRP) secreting neurons (see Stock No. 012899), this mutant mouse strain may be useful in studies of energy balance.
A targeting vector was designed to insert loxP sites flanking exon 2 of the solute carrier family 32 (sodium-dependant inorganic phosphate cotransporter), member 1 (Slc32a1 or Vgat) gene, followed by an frt-flanked kanamycin/neomycin (kan/neo) resistance cassette. The construct was electroporated into 129S6/SvEvTac-derived W4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into 129S6 blastocysts and resulting chimeric males were bred to FVB/N or C57BL/6 females. Offspring carrying this Vglut2 allele, were bred with 129S4/SvJaeSor-Gt(ROSA)26Sortm1(FLP1)Dym/J (Stock No. 003946) mice carrying a flp-recombinase gene to delete the kan/neo cassette, and progeny were crossed to remove the flp-expressing mutation, resulting in a colony homozygous for the floxed-Vgat (Vgatflox) allele. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J inbred mice (Stock No. 000664) for at least one generation to establish the colony.

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.
