These Cdk knock-out mice exhibit unique lesions in the central nervous system associated with perinatal mortality. They are suitable for use in applications related to the study of brain development, neuronal differentiation, and neuronal cytoskeleton structure and organization.

Cdk5 is an important molecule for brain development and neuronal differentiation. Cdk null mice exhibit unique lesions in the central nervous system associated with perinatal mortality. The brains of mutant mice lack cortical laminar structure and cerebellar foliation. The large neurons in the brain stem and in the spinal cord show chromatolytic changes with accumulation of neurofilament immunoreactivity. They also exhibit neuronal migration abnormalities, cerebellar defoliation, NF accumulation neuronal bodies, and degenerated motor neurons.
Genomic clones of the mouse Cdk5 gene were isolated from a 129/SvJ mouse genomic library. Genomic fragments were used to construct the targeting vector, which carried a 0.8kb deletion including a part of exon III, and exons IV and V. The deletion was replaced by a neomycin resistance gene.

The strain is on a mixed B6;129 background. Heterozygous mice appear normal; homozygous mice either die in utero or within 12 hours after birth. Expected coat color from breeding:Black,Agouti

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided,
their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of
each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders
are needed. Animals typically ship between 10 and 14 weeks from the date of your order. If a second cryorecovery is needed in
order to provide the minimum number of animals, animals will ship within 25 weeks.
The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
