Information from provider

ProviderKlaus WILLECKE
Provider affiliationMolekulargenetik, Institut fuer Genetik, Universitaet Bonn
Genetic informationExon 2, including the whole open reading frame of Cx30 (Gjb6), is homologously replaced by the lacZ open reading frame. The selection marker gene (neo) is maintained in the genome.
Phenotypic informationNon syndromic deafness.
Breeding historyAfter blastocyst injection the chimeras were bred with C57BL/6NCrl to obtain brown coat coloured offspring. This brown offspring was backcrossed to C57BL/6NCrl more than three times.

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).
