BRC No. | RBRC01345 |
Type | Targeted Mutation Congenic![]() |
Species | Mus musculus |
Strain name | B6.129P2-Emx1<tm1.1(cre)Ito>/ItoRbrc |
Former Common name | Emx1-Cre KI delta neo |
H-2 Haplotype | |
ES Cell line | E14 [129P2/OlaHsd] |
Background strain | C57BL/6JJcl |
Appearance | Black [a/a B/B C/C] |
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] |
