Name: targeted mutation 3, Richard R Behringer
Alteration at locus: Knock-In
Transgene: cre (Bacteriophage P1)
Name: cre recombinase
Alteration at locus: Knock-In
IRES-Cre-pA FRT- flanked Pgk-neo-bpA cassette introduced into exon 5 of the Amhr2 locus.
ES Cell Line: AB1
Homozygous phenotype: Persistent Mullerian Duct Syndrome and infertility in males. Phenotype is similar to Amh and Amhr2 knockouts.
Heterozygous phenotype: None detected.
Founder genetic background: 129/SvEvBrd
Strain genetic background: 129/SvEvBrd x C57BL/6J mix
Strain Development: Backcrossed to C57BL/6J.
Strain Genetic Background Validation:
A sample from this MMRRC strain was analyzed using the Mouse Universal Genotyping Array (MUGA) and MMRRC computational tools were used to assess the genetic background. A summary of the data can be found here.

Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at firstname.lastname@example.org for more details.
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.
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.

Fee/unit (US $)
|EA||The email@example.com may assess additional fees for any special requests (e.g., specific age or weight of mice, etc.).|
|Aliquot||Approximate quantity3: 20-40 embryos / aliquot|
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 and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
