Related Genotype: Aw/Aw

Description
Mice homozygous for the Gja1tm1Kdr targeted mutation die at birth. The cause of death is a failure in pulmonary gas exchange caused by a swelling and blockage of the right ventricular outflow tract from the heart. The cardiac abnormality involves a delay in the normal looping of the ascending limb of the heart tube, which includes the right ventricle and the outflow tract. This predisposes homozygous mutant mice to malformations of the subpulmonary outflow tract and tricuspid valve. The mutation also predisposes mice to lens cataracts and causes a severe reduction of germ cell numbers in homozygous mutant mice of both sexes. Both neonatal and adult mice heterozygous for the Gja1tm1Kdr targeted mutation have slower ventricular epicardial conduction of paced beats in the heart.

Development
The Gja1tm1Kdr mutant strain was developed in the laboratory of Dr. Gerald Kidder and Dr. Janet Rossant at The University of Western Ontario. The 129X1/SvJ x 129S1/Sv-derived R1 ES cell line was used.

Cryopreserved. Ready for recovery. Please refer to pricing and supply notes for further information.

Supply Notes

  • Cryorecovery - Standard.
    We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. The total number of animals provided, their gender and genotype will vary. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 13 and 16 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

    Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
    Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).

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.
