Strain Development

Specific deletion of FAK in the anlage of the dorsal telendin- cephalon was accomplished by mating fak-flox mice to mice expressing Cre recombinase under the control of the endogenous emx1 promoter (Gorski et al., 2002). Received mice were tested using microsattelite analysis, and determined to be approximately N2 backcross to C57BL/6. The MMRRC will cryorecover using C57BL/6NHsd.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

MMRRC Item # Description Distribution Fee / Unit (US $) Units Notes
009967-UCD-EMBRYO Cryo-preserved embryos $1,038.00 / Non-Profit Aliquot Approximate quantity3 : 20-40 embryos / aliquot
009967-UCD-SPERM Cryo-preserved spermatozoa $546.25 / Non-Profit Aliquot Approximate quantity2
009967-UCD-RESUS Litter recovered from cryo-archive $3,033.00 / Non-Profit Litter Recovered litter1; additional fees for any special requests.

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
