Strain Development
The H2Kb and H2Db double knockout mice were generated by sequential gene targeting in embryonic stem cells of 129/Ola origin, disrupting the only two functional class Ia loci in the H2bhaplotype. For H2Kb, a targeting vector replaced exons 2–3, encoding the α1–α2 peptide-binding domains, with a PGK-driven HPRT minigene in opposite orientation; homologous recombinants were selected in HAT medium, confirmed by PCR and Southern blot, and transmitted through chimeras to the germline. The H2Db knockout was generated in parallel using an analogous strategy described previously. Mice carrying each individual knockout were backcrossed onto the C57BL/6 background, and double knockouts were derived by intercrossing single knockout lines and identifying meiotic recombinants carrying both disrupted loci. Homozygous H2KbDb⁻/⁻ mice thus lacked class Ia expression while retaining class Ib molecules, providing a unique model to assess CD8⁺ T cell repertoire development and viral responses in the absence of classical MHC class I.


Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain’s tissue samples taken when archived by or ordered from the assigned MMRRC Center.

Order Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

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.

The donor or their institution limits the distribution to non-profit institutions only.

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.

Units Notes
041472-MU-RESUS Litter recovered from cryo-archive $2,624.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

1 The distribution fee covers the expense of rederiving mice from a live mouse; 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 contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 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.

4 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.
