Strain Information

BRC No.RBRC05290
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129P2-Dscam<tm1.1Kzy>/A151Kzy
Former Common nameB6-Dscam KO#A151
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strain
Strain developmentExon 1 was removed by crossing with CAG-cre (B6 background). The mice were backcrossed to C57BL/6 over 21 times.
Strain descriptionDscam knockout mice. Dscam, Down syndrome cell adhesion molecule is a gene of neural Ig superfamily mediates cell adhesion and axon outgrowth. Homozygous mutant mice of C57BL/6 genetic background die within 24 hours after birth due to central respiratory defects. In BALB/c mixed background, Homozygous mutant mice are viable and survive to adulthood.
Colony maintenanceHeterozygote x Wild-type [C57BL/6NCrSlc]
