Provider affiliationSchool of Life Sciences, University of Sussex
Genetic informationExon 14 was replaced with one in which a point mutation (G to C) results in the amino acid substitution of serine for cysteine at position 1619 (C1619S); cre-mediated recombination removed the neomycin resistance cassette.
Phenotypic informationHomozygous:
In Tecta/ homozygotes, the tectorial membrane has a 'hump-backed' cross-sectional profile, a much reduced limbal attachment zone and the disruption of the marginal band is exacerbated relative to heterozygotes. High levels of Tecta are detected by immunofluorescence in the tectorial membrane.

Heterozygous:
In heterozygous mice inner ear phenotype shows malformation of the tectorial membrane, auditory brainstem response (ABR) thresholds elevated by 20-30 dB and an enhanced susceptibility to audiogenic seizure at low sound pressure level.
Breeding historyF1 mice from germline transmitting chimera were mated with a cre recombinase deleter line to remove the floxed neomycin resistance cassette and the F2 generation was then outbred to 129SvEv.

Order

Availabilities

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

  • Frozen sperm. 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).
