mCherry
Name: red fluorescent fluorophore, mCherry
Type: Gene
Species: Discosoma sp. (mushroom coral)
Chromosome:
Genetic Alterations
Random insertion of transgene containing a-MHC-loxP(mCherrySTOP)-loxP-TRPV4 construct. Exhibits cardiomyocyte expression of the mCherry fluorescent reporter; cre-mediated recombination results in excision of the mCherry (with STOP) sequence and subsequent cardiomyocyte expression of the Trpv4 ion channel.
Genotype Determination
Phenotype
Elevated expression of Trpv4 in cardiomyocytes in young mice with potential for an inducible phenotype.
Strain Development
The Tg(alpha-MHC-loxP-mCherrySTOP-loxP-TRPV4)1td transgenic construct was created using cDNA of mouse Trpv4, the pmCherryC1 vector, the pJFRC172 vector, and the vector containing the alpha-myosin heavy chain promoter. First, pmCherryC1 was digested using BglII-BamHI for removal of the multiple cloning site, followed by AgeI-MluI (with Klenow fragment) to excise the mCherry coding region and stop codons. The mCherrySTOP sequence was then subcloned into pJFRC172 (AgeI -SpeI with Klenow fragment) resulting in a floxed mCherrySTOP sequence. The loxP-mCherrySTOP-loxP coding sequence was amplified with PCR primers encoding SalI (forward) and MluI and SalI (reverse) restriction sites, and subcloned into the SalI site of the alpha-MHC vector to form alpha-MHC-loxP-mCherrySTOP-loxP. The Trpv4 coding sequence was then amplified from cDNA with forward and reverse primers encoding BssHII restriction sites, and was inserted into the MluI site of alpha-MHC-loxP-mCherrySTOP-loxP to form alpha-MHC-loxP-mCherrySTOP-loxP-TRPV4. The resulting ~10kb transgene was excised with BamHI, purified, and injected into one-cell mouse embryos for random insertion. Resulting pups were genotyped to confirm the presence of the transgene (Forward primer: 5’–GACGGCGAGTTCATCTACAAG–3’, Reverse primer: 5’–TTCCACGATGGTGTAGTCCTC–3’), and backcrossed to C57BL/6 mice for 9 generations.
Suggested Control Mice

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@missouri.edu. Older strains may not have this information.

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@missouri.edu for more information.

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

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.
