TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129S-Ahr<tm1Yfk>
Former Common nameAhR(C57BL6j)-/- mouse
H-2 Haplotype
ES Cell lineCCE/EK.CCE [129S/SvEv-Gpi1<c>]
Background strain
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Drs. Yoshiaki Fujii-Kuriyama and Junsei Mimura at Tohoku University in 1997. The mutant mice are backcrossed to C57BL/6.
Strain descriptionB6.129S-Ahr<tm1Yfk>. The aryl hydrocarbon receptor (AhR) (dioxin receptor) is a transcription factor that mediate to catalyze xenobiotic Phase I metabolism. Homozygous mutant mice shows a slightly slower growth rate compared than wild-types for the first few weeks of life.
Colony maintenanceBackcross to C57BL/6 (Heterozygote x C57BL/6JJcl)
