Information from provider

ProviderKlaus WILLECKE
Provider affiliationMolekulargenetik, Institut fuer Genetik, Universitaet Bonn
Genetic informationIn this mouse line the Cx30 (Gjb6) coding DNA is replaced by the Cx30T5M point mutation followed by an IRES-LacZ reporter DNA. The point mutation and the reporter gene are controlled by the endogenous Cx30 promoter.
Phenotypic informationHomozygous Cx30(T5M/T5M) mice exhibited an increase in their hearing thresholds.
Breeding historyFounder animals were backcrossed to C57BL/6 more than three times (more than 87.5%).

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).
