The targeting vector has been generated using C57BL/6J DNA and transfected into C57BL/6NTac ES cell line.
Edn2 exon 1 contains the translation initiation codon.
Exon 2 has been flanked by loxP sites.
The conditional KO allele has been generated after Flp-mediated recombination by crossing chimeras to a Flp-Deleter on a C57BL/6 background.
The conditional KO line has been subsequently backcrossed to C57BL/6NTac animals for at least 2 generations and the Flp-transgene was removed by segregation.
The constitutive KO allele can be generated by Cre-mediated recombination. Deletion of exon 2 should result in loss of function of the Edn2 gene by generating a frameshift (premature stop codon in exon 4).
The remaining recombination sites are located in intron regions of the genome.
Datamining and Design performed in 2006.
