These mice carry an ENU-induced mutation characterized by body tremors.
The Jackson Laboratory cannot guarantee that cryorecovery of strains from the discontinued NIH-funded Neuroscience Mutagenesis Facility (NMF) will be successful or that the anticipated phenotype or genotype will be obtained. The cryorecovery fee for this effort will not be refunded or prorated if the recovery is unsuccessful or is in any way unsatisfactory. Genotyping will be the responsibility of the Purchaser.Read More +
The mutants exhibit an intense body tremor observed during movement and rest by 4 weeks of age (mean 4.3+/-0.48 weeks; n=21). Standard pathology work-up on two mutants (30 days of age) revealed no abnormalities. Mutants of either sex have been produced, and the colony is maintained through regular breeding.
This phenotypic deviant was generated by ethylnitrosourea (ENU) mutagenesis in C57BL/6J males (Stock No. 000664), in the Neuroscience Mutagenesis facility at The Jackson Laboratory. Mutagenized males were crossed to C57BL/6J females; G3 descendants of the mutagenized males were selected for neurological impairment.
