Genetic Alterations
Recombineering was used to generate Calca targeting arms from a C57BL/6-derived bacterial artificial chromosome (BAC; RP24-136021). The start codon located in exon 2 is common to CGRPalpha and calictonin and was replaced with an Asic-LoxP-EGFPf-3x pA-LoxP-DTR-pA-Frt-PGK-NeoR-Frt-AscI. EGFPf = farnesylated enhanced GFP. DTR = human diphtheria toxin receptor. NeoR = neomycin resistance. The LoxP sites were oriented so that the first ATG encountered was in GFP or, after Cre recombinase-mediated excision, DTR.

    Strain Development
    High percentage chimeras were crossed to C57BL/6 females to establish germline transmission and then crossed to B6.Cg-Tg(ACTFLPe)9205Dym/J (JAX Strain #005703) to remove the Frt-flanked selection cassette Mice were then backcrossed to C57BL/6 to remove the ACTFLPe allele (removal confirmed by PCR) and then backcrossed to C57BL/6 mice for 8 generations to establish the CGRPalpha-GFP knock-in line. GFP expression was only detected in DRG neurons after removal of the PGK-NeoR selection cassette.
    Suggested Control Mice
    Wild-type littermates or C57BL/6J 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@med.unc.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_health@med.unc.edu.

    Breeding Scheme(s)

    Homozygous mice were crossed together to maintain the homozygosity or crossed with C57BL/6 mice to obtain heterozygous mice.

    Generation
    N8+ (C57BL/6), F16
    Overall Breeding Performance

    Fair - 2013-2015 breeding analysis by Center: 17.6% of breeder pens failed to produce litters, the successful ones produced an average of 3.6 litters each with 3.1 surviving to weaning (cannibalization was the predominant reason for non-survival).  Average age of female fertility decline was 27.5 weeks of age (range of 15-45 weeks).

    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@med.unc.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.

    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.
