Bnip3-KO mice: These were generated by replacing exons 2 and 3 with a neomycin resistance cassette. Recombinations were identified via southern blot.

Nix KO mice: Exons 4 to 6a, encoding the putative BH3 domain and the essential carboxyl-terminal transmembrane domain (22) of Nix, were targeted by flanking them with loxP sites, in combination with a frt-flanked neomycin phosphotransferase module to positively select putative homologous recombinant embryonic stem cells. Correctly targeted recombinants were identified by EcoRI restriction digest and Southern blot.
