Strain Description
Mice homozygous for the osteosclerotic spontaneous mutation (oc) can be recognized at about 10 days by failure of eruption of the incisors, clubbed feet, and circling behavior. Homozygous mutant mice may also have a kinked tail. They grow normally for about the first 10 days of life, then lose weight or at least fail to gain.
Strain Development
Tcirg1oc arose in a C57BL/6J stock in 1964. A Tcirg1oc/+ female was crossed to a gl/+ male. This is believed to have been an allele test with grey-lethal. The background of the gl/+ mouse is unknown, but it arrived at The Jackson Laboratory from George Jay in 1954 and may have been crossed to C3H once or twice. Then Tcirg1oc/+ sibling matings were continued until F10 at which time the inbreeding line was dying out. Subsequently, Tcirg1oc/+ or ovarian transplants were then used at each generation to breed to B6C3Fe-a/aF1 hybrids. In 1984 at N20 the stock was put into the Frozen Embryo Repository.

Cryorecovery of Strains Needing Progeny Testing. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two untested males and two untested females (two pairs) will be recovered, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the overall recovery time to approximately 25 weeks. However, all pups recovered will be sent.
Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available. This type of testing involves breeding the recovered animals and assessing the phenotype of the offspring in order to identify animals carrying the mutation of interest. We can perform the progeny testing for you as a service or we can ship all recovered animals (at least two untested pairs) to you for progeny testing at your facility. If you perform the progeny testing, there is NO guarantee that a carrier will be identified. If we perform progeny testing as a service, additional breeding time will be required. In this case, when a male and female (one pair) are identified that carry the mutation, they and their offspring will be shipped. Delivery time for strains requiring progeny testing often exceeds 25 weeks and may take 12 months or more due to the difficulties in breeding some strains. The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation. Please note that identified pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Please contact Customer Service for more information on the cost of progeny testing for a strain: Tel: 1-800-422-6423 or 1-207-288-5845.Cryorecovery to establish a Dedicated Supply for greater quantities of mice One to two pairs will be recovered to establish a Dedicated Supply of mice.

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene
genotyping programs to ensure the genetic background of JAX
® Mice strains as
well as the genotypes of strains with identified molecular mutations.
JAX
® Mice strains are only made available to researchers after meeting our
standards. However, the phenotype of each strain may not be fully
characterized and/or captured in the strain data sheets.
Therefore, we
cannot guarantee a strain's phenotype will meet all expectations. To
ensure that JAX
® Mice will meet the needs of individual research projects
or when requesting a strain that is new to your research, we suggest ordering
and performing tests on a small number of mice to determine suitability for
your particular project.
