Strain Information

Frem1bat
Name: Fras1 related extracellular matrix protein 1; bat
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 4
Alteration at locus: Chemically Induced
Frem1
Name: Fras1 related extracellular matrix protein 1
Synonyms: heb, eyem02Jus, eyes2, QBRICK, crf11
Type: Gene
Species: Mouse
Chromosome: 4
Alteration at locus: Chemically Induced
NCBI: 329872
Homologene: 27049
Genetic Alterations
ENU-induced T to C transition in the donor splice site of intron 25 (GTACT->GCACT) of the Frem1 gene (position 85133 in the Genbank genomic region NC_000070 for linear genomic DNA sequence of Frem1). The mutation results in skipping of exon 25, and destroys the reading frame thereafter. Thus, 39 nucleotides from exon 26 are transcribed, encoding 12 aberrant amino acids, followed by a premature stop codon. No splicing between exons 25 and 26 is detected.
Genotype Determination
Phenotype
Homozygous: The bat phenotype was identified as a visible phenotype among ENU-induced G3 mice. Homozygous bat mice display a range of defects including cryptophthalmos (skin covering the globe of the eye), occasional hindlimb syndactyly (fusion of fingers or toes), and renal anomalies (unilateral agenesis of the kidney). From 13.5 dpc (days post conception), bat embryos develop subepidermal blisters (

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@ucdavis.edu. Older strains may not have this information.

Colony and Husbandry Information

Colony Surveillance Program and Current Health Reports

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@ucdavis.edu.

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 mmrrc@ucdavis.edu 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.

Units Notes
030387-UCD-EMBRYO Cryo-preserved embryos $1,038.00 / Non-Profit Aliquot Approximate quantity2 : 20-40 embryos / aliquot
030387-UCD-SPERM Cryo-preserved spermatozoa $546.25 / Non-Profit Aliquot Approximate quantity3
030387-UCD-RESUS Litter recovered from cryo-archive $4,044.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.

1 The distribution fee covers the expense of rederiving mice from a live mouse; 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 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.

3 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.

4 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.
