The BXD RI strains are used to study the genetics of behavioral phenotypes including alcohol and drug addiction, stress, and locomotor activity.The BXD set of RI strains also are used in the genetic analysis of numerous complex or potentially complex physiologic phenotypes including differences in organ weight and bone mineral density.
The strain distribution pattern (SDP) for the BXD RI strains is available through the Mouse Genome Informatics Contributed Data Sets and Gene Network. Additional tools and information are presented through the Mouse Phenome Database Specialized Strain Panel Query Form, and Gene Network.
The Jackson Laboratory live colony was a challenging breeder / very poor breeder. It exhibited a high incidence of non-productive matings and when productive, the litters were small [May 2021]. See our General Husbandry Tips.
Development
The BXD set of RI strains was developed in the laboratory of Benjamin Taylor and was transferred to The Jackson Laboratory from Dr. Taylor's research colony upon his retirement. Of 42 BXD RI strains originally derived from the C57BL/6J (Stock No. 000664) and DBA/2J (Stock No. 000671), a number have become extinct over the years. The other BXD RI strains now being distributed are listed under "Related Recombinant Inbred Strains."
In 1982/83 after BXD-20/Ty had been intercrossed approximately 48 times (uncertain of exact date and filial generation number) one F48 BXD20/Ty male was outcrossed once to a single C57BL/6J female. The N1 offspring from this cross were then backcrossed to their sire, and this process was repeated 4 times. In total the outcross to C57BL/6J was followed by 4 consecutive backcrosses to the same F48 BXD-20/Ty male. The line was then intercrossed and after 20 additional generations of inbreeding efforts began to cryopreserve the strain. The generation number of the cryopreserved mice F48N5F75+10p.

Payment Terms and Conditions
Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.
The Jackson Laboratory's Genotyping Promise
The Jackson Laboratory ensures the genetic quality and genotyping of JAX® Mice strains before making them available to researchers. However, phenotypes may vary due to environmental conditions and may not be fully characterized. Phenotype descriptions are based on published data, and JAX does not guarantee phenotype or breeding performance.
To ensure JAX® Mice meet your research needs, we recommend:
- Genotyping mutant mice upon arrival.
- Performing pilot experiments on a small number of mice.
- Ordering more than one breeding pair to establish your colony and avoid delays.
