Additional information on Congenic nomenclature. Species laboratory mouse Donating Investigator Elizabeth Simpson, University of British Columbia Description
These Ple183-EGFP;mEMS2742 mice have the Ple183-EGFP transgene targeted as a single copy "knockin" into the upstream region of hypoxanthine guanine phosphoribosyl transferase 1 (Hprt1) locus on the X chromosome. Heterozygous females and hemizygous males are viable and fertile, with the promoter/regulatory regions of the human S100 calcium binding protein B (S100B) gene directing expression of an enhanced green fluorescent protein (EGFP). These Ple183-EGFP;mEMS2742 mice may be useful in studying S100B-expressing cells in the brain and diseases affecting the brain.For Ple183-EGFP;mEMS2742 expression information, see The Pleiades Promoter Project website (Ple183 Promoter (pEMS1382)).
The donating investigator reports:
Numerous EGFP positive Bergmann glial cells are observed throughout the cerebellum via immunostaining. No EGFP signal above background level could be observed in other regions of the brain, such as cortex and brainstem.These mice were created and deposited by The Pleiades Promoter Project (Centre for Molecular Medicine and Therapeutics, University of British Columbia).
Development
The Ple183-EGFP transgene (pEMS1382) was designed with the 1384 bp Ple183 minipromoter (S100β-A; derived from a subsection of the promoter from the human S100 calcium binding protein B (S100B) 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 Hprt1b-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 Hprt1b-m3 mutation [originally derived from 129P2/OlaHsd-derived E14TG2a embryonic stem cells] X 129S-Gt(ROSA)26Sortm1Sor heterozygous males (see Stock No. 002171 and 003310, respectively)). Correctly targeted embryonic stem cells were microinjected into recipient mice cells. The resulting chimeric males (founder line mEMS2742) were bred to B6(Cg)-Tyrc-2J/J females (B6-albino; Stock No. 000058) to establish the mutant colony. These Ple183-EGFP;mEMS2742 mutant mice were bred with C57BL/6J wildtype mice for four generations. Black mice without the Gt(ROSA)26Sortm1Sor mutation and segregating for the Tyrc-2J mutation were sent to The Jackson Laboratory. Upon arrival, Ple183-EGFP;mEMS2742 mutant mice were bred with C57BL/6J inbred mice (Stock No. 000664) for at least one generation to establish the colony.For more information, see The Pleiades Promoter Project website (Ple183 Promoter (pEMS1382)).

Estimated Available for Sale Date:
Please note: Estimated available for sale dates are provided to keep customers better informed on strains under development. Please note that our Colony Managers routinely monitor the target date and edit it based on breeding performance and other factors. The length of time it takes to make a new strain available for sale depends on genotype, age, number of animals sent by the Donating Investigator, breeding performance, additional strain development (backcrossing, making homozygous), and anticipated demand for the strain/interest registered.
