Allele Symbol: Frem2Gt(KST252)Byg Name: gene trap KST252, BayGenomics Alteration at locus: Gene Trap |
Genetic Alterations:
This sequence was obtained by 5'RACE PCR from a 129P2/OlaHsd mouse embryonic stem (ES) cell line (E14TG2a.4) with an insertional mutation from gene trap vector pGT1TMpfs, (Properly spliced).
Genotype Determination:
ES Cell Line: E14Tg2a.4 derived from 129P2/OlaHsd
Strain Description
Phenotype
These mice were not phenotyped prior to cryopreservation, nor were they mated to produce homozygous offspring, therefore the homozygous phenotype is unknown.
Founder genetic background: 129P2/OlaHsd
Strain genetic background: B6;129P2
Strain Development: The ES cell line was injected into C57BL/6J host blastocysts to generate chimeras. The chimeras were then crossed with C57BL/6J mice to determine germline transmission. The resulting heterozygous males were cryoarchived for distribution.
Suggested Control Mice:
- Wild-type littermates
Research Applications
- Research Tools
Strain Origin
Donor: MMRRC at University of California, Davis

Appearance
Coat color: Agouti/Black
(Note: if sib-mated, it is possible to get pink-eyed chinchilla, the color of the 129P2/Ola, or other mixed variations.)

Breeding
MMRRC Breeding System: Backcross or Inbreeding
Breeding Scheme(s):
- C57BL/6J female x Heterozygous male or reciprocal
- Wild-type female x Heterozygous male sibling or reciprocal
Generation: N2
Overall Breeding Performance: Good
Reproductive Statistics
| Viability and Fertility: | Female | Male |
|---|---|---|
| Homozygotes are viable: | Unknown* | Unknown* |
| Homozygotes are fertile: | Unknown* | Unknown* |
| Heterozygotes are fertile: | Unknown* | Yes |
| Age Reproductive Decline: | Unknown* | 36 weeks |
Average litter size: 8
Recommended wean age: 3 weeks
Special Considerations
*During development at MMRRC at UCD, mating was done with heterozygous males; viability, fertility and other breeding statistics for heterozygous females and homozygotes are unverified, but presumably would be similar to the background strain.
Health Status Report
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 mmrrc@ucdavis.edu.
Order Request Information
Availability Level:
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
Conditions of Distribution:
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.
Fees:
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 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.
