 1 Appearance black  
Genotype a/a  
Strain development Developed by Kenya Honda and Tadatsugu Taniguchi, Graduate School of Medicine and Faculty of Medicine, University of Tokyo in 2001. The knockout construct was electroporated into E14 ES cells derived from 129P2/OlaHsd. C57BL/6 semicongenic strain.  
Strain description IRF7 knockout mice. Exon 2 and 3 of Irf7 gene were replaced with a PGK-beta-geo cassette. Homozygous mutant mice are vulnerable to viral infection with a decreased serum interferon level.  
Colony maintenance Homozygote x Homozygote
