RBRC No. RBRC00808
Type Targeted MutationCartagena
Species Mus musculus
Strain name B6.129P2-Emx1<tm1(cre)Ito>/ItoRbrc
Former Common name Emx1-Cre
H-2 Haplotype No Data
ES cell line E14 [129P2/OlaHsd]
Donor strain 129P2/OlaHsd via E14 ES cell line
Background strain C57BL/6JJcl
1 Appearance black (a/a B/B C/C)
Genotype No Data
Strain development Developed 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 description Emx1-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 maintenance Homozygote x Homozygote [or Crossing to C57BL/6JJcl]
