Nfe2l2 - Model 13107 - cKO

Conditional Knockout

Cryopreserved Model
This line is cryopreserved and requires cryorecovery.

C57BL/6 Background

  • Model #
  • Genotype
  • Nomenclature
  • 13107
    C57BL/6-Nfe2l2 tm1.1 Mrl
  • The targeting vector has been generated using C57BL/6J DNA and transfected into TaconicArtemis C57BL/6N Tac ES cell line.
  • Nfe2l2 exon 1 contains the translation initiation codon.
  • Exons 2 to 5 have been flanked by loxP sites (size of loxP-flanked region is 5.0 kb).
  • A polyadenylation signal (hGHpA: human Growth Hormone polyadenylation signal) has been inserted 3' of the distal loxP site in order to stop transcription in the constitutive KO allele.
  • The conditional KO allele has been generated after Flp-mediated removal of selection marker by crossing chimeras to a Flp-Deleter on a C57BL/6 background.
  • The conditional KO line has been derived using C57BL/6NTac animals and the Flp-transgene was removed by segregation.
  • Deletion of exons 2 to 5 should result in loss of function of the Nfe2l2 gene by deleting most of the gene.
  • The remaining recombination sites are located in non-conserved regions of the genome.
  • The constitutive KO allele is available as line 13143.
  • Datamining and Design performed in 2012.

GEM Collection models exist as cryopreserved materials. Models can typically be recovered and delivered to customers within 14-16 weeks after order receipt. Customers will receive:

  • A minimum of four (4) mice mutant for the selected mutation. In rare cases where the cryopreserved material also contains a recombinase gene, this may be reduced to 1-2 mutant mice.
  • Validated genotyping protocols
  • Animal health report. Mice will meet Taconic's Murine Pathogen Free™ (MPF™) health standard.

Please note that in rare instances (2%) cryorecovery may prove to be difficult, either extending timeline or ultimately successful recovery.
Customers may purchase this model by signing the appropriate Terms of Sale (below) and providing a PO. The GEM Collection Commercial and Academic Terms of Sale grant perpetual use rights.
