FVB.Cg-Smn1^tm2Mrph/J

Stock number: 007955
Research areas: Developmental Biology Research, Neurobiology Research

Description

This strain functions as a reporter strain for Smn1 (survival motor neuron 1) in the heterozygous state. Exons 1 through 8 of the mouse Smn1 gene (12.8 kb) were replaced with lacZ and an FRT site remaining from the deletion of a selection marker. This allele is a functional null and homozygous animals are embryonic lethal.

Importation of this model was supported by the Spinal Muscular Atrophy Foundation.

Development

Exons 1 through 8 of the mouse Smn1 (survival motor neuron 1) gene (12.8 kb) were replaced with lacZ and an FRT site remaining from the deletion of a selection marker. 129S6/SvEvTac and C57BL/6Tac derived F1H4 ES cells were used. The mice were then backcrossed to FVB/NJ for at least 5 generations.
