Alteration at locus: Knock-In
Name: gene trap ROSA 26, Philippe Soriano
Alteration at locus: Knock-In
ES Cell Line: E14 derived from 129P2/OlaHsd
Hemizygous mice have increased mineralization in calvaria.
Strain of Origin: 129P2/OlaHsd
Strain genetic background: B6.129P2
Strain Development: E14Tg2A.4 mouse embryonic stem cells were electroporated with a Rosa26 vector carrying the combined EF1a-tTA and TetO-mCh-Rs1 transgenes in a single construct. Mice were generated by blastocyst injection, and chimeras were backcrossed to C57BL/6.
Suggested Control Mice: Wild-type littermates or C57BL/6
Donor: Bruce Conklin, M.D., Gladstone Institute of Cardiovascular Disease
Hsiao EC, Nguyen TD, Ng JK, Scott MJ, Chang WC, Zahed H, Conklin BR. Constitutive Gs activation using a single-construct tetracycline-inducible expression system in embryonic stem cells and mice. Stem Cell Res Ther. 2011 Mar 4;2(2):11. (Medline PMID: 21375737).
Doxycycline diet = BioServ DoxDiet 200 mg/kg. No embryonic lethality was identifed when mated off of doxycycline (with transgenes induced). However, the donor recommends maintining the mouse line on doxycycline (or maintaining the ES cell line in doxy-containing media) to prevent any unexpected effects from Rs1 expression.

Fee/unit (US $)
|Litter||Recovered litter1; additional fees for any special requests.|
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.
