BRC No.RBRC10466
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameMRL.Cg-Xkr8<tm1.2Osa>
Former Common nameXkr8-/- MRL mice
H-2 Haplotype
ES Cell lineBruce 4 [B6.Cg-Thy1<a>]
Background strain
Appearance
Strain developmentDeveloped by Shigekazu Ngata at Osaka University in 2013. Bruce 4 ES cell line was used. Neomycin resistance gene was removed by crossing CAG-Cre mice. Exon 3 was deleted. This strain was backcrossed to a MRL strain for 5 generations. Analysis of SNP markers showed that 98% of them are derived from MRL.
Strain descriptionXkr8 (X-linked Kx blood group related 8) knockout mice. MRL congenic strain. Male mutants are infertile.
Colony maintenance
References
