Stock Number : 032929-JAX

Gene Information

(provided by MGI)
Allele Symbol: Hprttm18(Ple90-EGFP)Ems
Name: targeted mutation 18, Elizabeth M Simpson
Alteration at locus: Targeted Mutation
Reporter: EGFP (Aequorea victoria (jellyfish))
Name: enhanced green fluorescent protein
Alteration at locus: Targeted Mutation
Promoter: GFAP (Homo sapien (human))
Name: glial fibrillary acidic protein
Chromosome: 17
Alteration at locus: Targeted Mutation
Genetic Alterations:

The Ple90-EGFP transgene (pEMS1377) was designed with the 1433 bp Ple90 MiniPromoter (derived from a putative upstream regulatory region and a portion of the promoter of the human glial fibrillary acidic protein (GFAP) gene) upstream of a minimal F5 mutant-frt site, an enhanced green fluorescent protein (with mutated TAA->TTA stop), a nuclear localization signal, a second minimal frt site, an SV40 early polyA signal, and a human HPRT complementary sequence (containing exon1, intron1, exon2, and part of intron2). This construct was targeted as a single copy knockin to the Hprtb-m3 mutant locus on the X chromosome via electroporation into mEMS1204 embryonic stem cells (generated from F1 generation male pups born of C57BL/6-congenic females homozygous for a Hprtb-m3 mutation [originally derived from 129P2/OlaHsd-derived E14TG2a embryonic stem cells] X 129S-Gt(ROSA)26Sortm1Sor heterozygous males.

Genotype Determination:

ES Cell Line: mEMS21TG2A


Homozygous: Not evaluated

Heterozygous: These Ple90-EGFP;mEMS1899 mice have the Ple90-EGFP transgene targeted as a single copy "knockin" into the upstream region of hypoxanthine guanine phosphoribosyl transferase (Hprt) locus on the X chromosome. Heterozygous females and hemizygous males are viable and fertile, with the promoter/regulatory regions of the human glial fibrillary acidic protein (GFAP) gene directing expression of enhanced green fluorescent protein (EGFP). These Ple90-EGFP;mEMS1899 mice may be useful in studying GFAP-expressing cells in the brain and diseases affecting the brain.

The donating investigator reports: The expression pattern of the Ple90 MiniPromoter is quite similar to the expression of Ple88; with broad expression in glial cellular profiles throughout the brain and spinal cord. Numerous astroglial profiles are seen in the cortical grey and white matter and in the cerebellum the full extent of Bergmann glial processes are highlighted with anti-EGFP immunocytochemistry. EGFP-immunoreactivity is most prominent in the cell bodies across all regions, with a subpopulation of cells showing a halo of process staining.

Strain of Origin: C57BL/6 and 129

Strain genetic background: B6.129P2(Cg)

Strain Development: Correctly targeted embryonic stem cells were microinjected into recipient mice cells. The resulting chimeric males (founder line mEMS1899) were bred to B6(Cg)-Tyrc-2J/J females (B6-albino) to establish the mutant colony. These Ple90-EGFP;mEMS1899 mutant mice were bred with C57BL/6J wild-type mice for five generations. Black mice without the Gt(ROSA)26Sortm1Sor or Tyrc-2J mutations were sent to the MMRRC. Upon arrival, Ple90-EGFP;mEMS1899 mutant mice were used to cryopreserve sperm. When rederiving a live colony, sperm will be used along with oocytes from C57BL/6J inbred mice to generate obligate heterozygous females, and these females will be bred at least one generation to C57BL/6J inbred mice to establish the colony.

Suggested Control Mice: Wild-type littermates or C57BL/6J mice

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
