Strain nameB6.129P2-Chd8<tm2.1Kei>
Former Common nameChd8L KO
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strainC57BL/6JJcl
Strain developmentDeposited by Keiichi Nakayama, Medical Institute of Bioregulation, Kyusyu University in 2016. E14(129P2/OlaHsd) ES cell line was used. C57BL/6 congenic strain.
Strain descriptionChd8l (chromodomain helicase DNA binding protein 8 long isoform) knockout mice. Homozygous mutants are lethal. A pair of loxP sites with a neo gene cassette flanking exons 11 to 13, and then these exons were deleted by Cre expression in ES cells. Mouse strain carrying deletion of both long isoform (Chd8l) and short isoform (Chd8s) is available as RBRC09758.
