Appearance

Related Genotype: A/A Epha4rb/Epha4rb

agouti, unaffected
Related Genotype: A/A Epha4rb/+ or A/A +/?

Important Note
The C3H/HeSnJ background strain is homozygous for the retinal degeneration mutation Pde6brd1.

Strain Description
Mice homozygous for the rb allele of Epha4 can be visibly identified by 2.5 - 3 weeks of age by a constant hopping gait of the hind limbs; the forelimbs may show a hopping gait or move normally. When picked up by the tail homozygotes clasp their hindlimbs and show reduced ability to hold on to an edge; forelimbs show normal strength.

Strain Development
The recessive rb mutation of Epha4 arose spontaneously on the C57BL/6J inbred strain at the Jackson Laboratory in 1964. The rb allele was transferred to the C3H/HeSnJ background and has been maintained for many generations by backcrossing mice homozygous for Epha4rb to C3H/HeSnJ mice, then intercrossing the progeny. In 2004 this strain reached N37.

Supply Details

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to the Supply Notes for further information.
Supply Notes Cryorecovery - Standard.
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 males and two females (two pairs) will be provided, 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 delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that 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. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

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. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services: Tel: 1-800-422-6423 or 1-207-288-5845; Email: jaxservices@jax.org.

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.
