Information from provider

ProviderAntonio Simeone
Provider affiliationCeinge Biotecnologie Avanzate
Additional ownerPhilippe Brulet, Unité d'Embryologie Moléculaire, Centre National de la Recherche Scientifique (CNRS), Institut Pasteur, Paris, France
Genetic informationOtx1 exon 1 and 2 are replaced with lacZ gene by homologous recombination.
Phenotypic informationHomozygous mice show spontaneous epileptic behaviour and adult brain is reduced in weight by about 25%; females lack parental care.
Breeding historyTargeted mutation was introduced in HM-1 ES cells. Mice were always maintained in a mixed C57BL/6 and DBA/2 genetic background.

Order

Availabilities

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

  • Frozen embryos. Delivered in 4 weeks (after paperwork in place). €1740*
  • Rederivation of mice from frozen stock, delivery time available upon request . €3880*

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).
