BRC No.RBRC06047
TypeTargeted Mutation CongenicCartagena
SpeciesMus musculus
Strain nameB6.Cg-Hes1<tm1Imayo>
Former Common nameB6-Hes1-floxed ; B6-Hes1 floxed
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strain
Strain developmentDeveloped by Itaru Imayoshi and Ryoichiro Kageyama, Institute for Virus Research, Kyoto University in 2007. TT2 ES cells were used. The mutant mice were crossed to C57BL/6 for 6 times.
Strain descriptionHes1 gene floxed mice. LoxP sequences were knocked into the first intron and downstream of 3'UTR of Hes1 gene for conditional knock-out study. PGK-Neo sequence was removed.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]
