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
When using the Cdk5- mouse strain in a publication, please cite the originating article(s) and include JAX stock #003536 in your Materials and Methods section.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.
