BRC No.RBRC01897
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129P2-Sox2<tm1Okud>
Former Common nameFloxed Sox2 mice
H-2 Haplotype
ES Cell lineE14TG2a [129P2/OlaHsd]
Background strain
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Akihiko Okuda, Research Center for Genomic Medicine, Saitama Medical University in 2004. C57BL/6 background.
Strain descriptionSox2 gene is a member of the SRY-related HMG box gene family that encode transcription factors with a single HMG DNA-binding domain, expresses in multipotent neural stem cells at all stages of mouse ontogeny. Sox2 ORF was replaced with IREShygTKpA cassette flanked by loxP sites. Conditional Sox2 deficient mice can be generated by crossing this mice with tissue-specific Cre mice.
Colony maintenanceHeterozygote (female) x Wild-type (male) [C57BL/6JJcl]. Fertility of heterozygous male is low.
