Chromosome:
Alteration at locus: Transgenic
cre
Name: cre recombinase
Type: Gene
Species: Enterobacteria phage P1 (bacteriophage P1)
Chromosome:
Alteration at locus: Transgenic
Lrat
Name: lecithin-retinol acyltransferase (phosphatidylcholine-retinol-O-acyltransferase)
Synonyms: 1300010A18Rik
Type: Gene
Species: Mouse
Chromosome: 3
Alteration at locus: Transgenic
NCBI: 79235
HGNC: HGNC:6685
Homologene: 3483
Genetic Alterations
A bacterial artificial chromosome containing the Lrat gene was modified by recombineering to insert a cre recombinase:polyA:FRT flanked neomycin cassette (with 60-bp overhangs) into the ATG site of the Lrat gene sequence. The neomycin cassette was removed by arabinose-induced flippase.
Genotype Determination
ES Cell Line
Not applicable
Phenotype
Hemizygous mice are viable and fertile. Homozygote viability/fertility has not been assessed. LratCre females, but not males, must be used for breeding; breeding through the male may permanently alter cre activity. Both males and females can be used in experiments.

Strain Development
The BAC was microinjected into the pronuclei of fertilized CBA x C57BL/6J oocytes. Founder line 1 exhibited the highest level of expression in the liver and hepatic stellate cells. This founder was bred to C57BL/6J mice. Mice were backcrossed to C57BL/6J for at least 7 generations. Upon arrival, sperm was cryopreserved. To establish the live colony, an aliquot of frozen sperm was used to fertilize C57BL/6J oocytes.
Suggested Control Mice
C57BL/6J
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 csmmrrc@jax.org. Older strains may not have this information.

Colony and Husbandry Information

Hemizygous mice are viable and fertile. Homozygote viability/fertility has not been assessed. The donating investigator indicates that Cre inactivation or Cre activity may occur in the male germline. LratCre females, but not males, must be used for breeding; breeding through the male may permanently alter cre activity.

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.

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.
