Genetic Alterations
The pRosa26-228 AR8 TA-Cherry vector was made using a basal exchange vector which contains a 5.166 kb sequence from the ROSA26 locus, Lox71/Lox2272 sites, and a FRT site (FLP flanked Pgk-hygR gene) cassette that is used for positive selection of ES cells after RMCE. An upstream FLP flanked hygromycin selection cassette was subsequently removed by flp recombinase. Eventually, the Rosa26 gene sequence (-228 to +81) was replaced by the Foxh1/Smad2-dependent, Mix2-derived Activin response element (AR8) fused to a TATA-mCherry reporter.

Strain Development
TL1 ES Cells containing a targeted vector were microinjected into blastocysts of C57BL/6J mice. The resulting chimeric male offsprings were bred with C57BL/6J female mice to acheive germline transmission. Then, these mice were crossed with ACTB:FLPe mice to remove the hygromycin resistant gene and then backcrossed for 7 generations with C57BL/6J.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to csmmrrc@jax.org for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of rederiving mice from a live mouse; 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 contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 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.

4 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.
