Allele Symbol: Aregtm1Dle
Name: targeted mutation 1, David C Lee
Alteration at locus: Knockout
Gene Symbol: Areg
Alteration at locus: Knockout
ES Cell Line:
Homozygous phenotype: Defective mammary
gland ductal outgrowth. Young, uniparous females usually cannot lactate,
older multiparous females often can lactate. Impaired response to partial
Heterozygous phenotype: None
Strain of Origin: C57BL/6J X 129/Sv
Strain genetic background: C57BL/6J X 129/Sv
Strain Development: Chimeras derived from targeted mutations
in Areg were mated to C57BL/6, and transmitting F1s were interbred or
bred to C57BL/6. After several generations, homozygous nulls have been
maintained by intercrossing for several years.
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.

Suggested Control Mice:
Donor: David C. Lee, Ph.D., University of North Carolina, Chapel Hill
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
Fee/unit (US $)
|Litter||Recovered litter1; additional fees for any special requests.|
|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.
