These mice carry the spontaneous H2-Kbm8 mutation and may be useful in studies of MHC structure and function, and T cell development and function.

The H2-Kbm8 (H-2bh) variant allele mutation arose spontaneously in a male C57BL/6Kh mouse and contains four amino acid substitutions. Homozygotes are viable and fertile. Mice congenic for H2 haplotypes are widely used in immunologic research and often vary in immune response and pathogen susceptibility from the recipient strain.
The H2-Kbm8 mutation arose spontaneously in a male C57BL/6Kh mouse (Melvold et al. Immunogenetics. 1982;15(2):177-85). There are 4 amino acid substitutions in this mutation: at amino acid position 22 (Tyr to Phe); amino acid position 23 (Met to Ile); amino acid position 24 (Glu to Ser); and amino acid position 30 (Asp to Asn). The strain was maintained as homozygote on the C57BL/6 background and may contain incidental BALB/c. Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6J (Stock No. 000664) at least once to establish the colony.

Molecular Note | Sequence analysis revealed that this mutation comprises 7 nucleotide substitutions within a 24 base pair stretch compared with the parental genome sequence. The consequence is 4 amino acid substitutions: at amino acid position 22 (Tyr to Phe); amino acid position 23 (Met to Ile); amino acid position 24 (Glu to Ser); and amino acid position 30 (Asp to Asn). |
When maintaining a live colony, these mice can be bred as homozygotes.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
