Strain Information

Image
BRC No.RBRC00808
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129P2-Emx1<tm1(cre)Ito>/ItoRbrc
Former Common nameEmx1-Cre
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strainC57BL/6JJcl
Appearanceblack (a/a B/B C/C)
Strain developmentDeveloped by Takuji Iwasato and Shigeyoshi Itohara, RIKEN Brain Science Institute. E14 ES cells were used to generate the mutant mice. The mice were backcrossed to C57BL/6J.
Strain descriptionEmx1-cre knock-in mice. neo type (inserted a cre recombinase gene and a frt flanked PGK-neo cassette into Emx1 gene)(RBRC00808), delta neo type (removed the pgk-neo cassette by FLP mediated recombination)(RBRC01345). The expression of cre recombinase was observed in dorsal telencephalon, neocortex, hippocampus, and olfactory bulb. In the delta neo type (RBRC01345), no ectopic cre expression was detected. Homozygous mice are viable and fertile.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]
