Information from provider

ProviderMarkus Missler
Provider affiliationDepartment of Anatomy and Molecular Neurobiology, Westfälische Wilhelms-University Münster
Genetic informationA neo cassette replaced the first exon, which contains the complete 5' UTR, start codon, signal peptide and the first LNS (Laminin alpha, Neurexins, and Sex hormone-binding globulin) domain. Immunoblotting of mutant brain confirmed lack of protein.
Phenotypic informationMice homozygous for a knock-out allele show a 30-40% decrease in body weight and their inhibitory postsynaptic currents (IPSCs) are decreased in cortical slice cultures.
Breeding historyBackcrossed for 8 generations to C57BL/6J.

Order

Availabilities

Requesting frozen sperm or embryos is generally advisable wherever possible, in order to minimise the shipment of live mice.

Due to the dynamic nature of our processes strain availability may change at short notice. The local repository manager will advise you in these circumstances.

* In addition users have to cover all the shipping costs (including the cost for returning dry-shippers, where applicable).
