Genetic Alterations
This is a novel reporter mouse expressing a fluorescent timer protein (FT-Slow) fused to histone H2B (gene: H2BC9). H2B-FT-Slow is under the control of a doxycycline-inducible promoter (TetO) and knocked into the mouse genome at the HPRT locus on the X chromosome. The mouse also has an rtTA transgene knocked into the Rosa26 locus. This mutant form of rtTA termed M2 has five amino acid substitutions in the tetR moiety of tTA, predicting amino acid exchanges S12G, E19G, A56P, D148E and H179R. Mice are homozygous for the rtTA allele and either homozygous (females) or hemizygous (males) for the iH2B-FT-Slow allele.

Compared to mCherry (RefSeq GenBank AHW57114.1), FT-Slow has genetic alterations predicting the following amino acid substitutions: M23E, E35V, K75R, L88W, A180V.
ES Cell Line
  • Hprttm2(tetO/CMV-H2B/mediumFT)Sguo allele - A2Lox.cre derived from 129P2/OlaHsd
  • Gt(ROSA)26Sortm1(rtTA*M2)Jae allele - KH2 derived from (C57BL/6 x 129S4/SvJae)F1
Phenotype
None/Normal/Wild-type.

Conditional phenotype: The mouse has whole-body expression of a fluorescent fusion reporter, TetO-H2B-FT-Medium, when induced with doxycycline drinking water.

Strain Development

Correctly targeted blastocysts were implanted into C57BL/6 females. High-degree chimeric male offspring were selected by coat color and backcrossed onto C57BL/6J to N6+. The rtTA allele was introduced by cross-breeding with a strain on C57BL/6J background. Subsequent GQC results indicate that it is segregating 129 and an unknown. The genetic background was hence revised to STOCK.

Suggested Control Mice
To determine the negative vs. positive threshold in fluorescence assays in colorless (negative) control tissue, use C57BL/6J mice carrying Rosa26::rtTA alleles
MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact csmmrrc@jax.org. Older strains may not have this information.

Colony and Husbandry Information

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email csmmrrc@jax.org.

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.

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

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.

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.
