    Strain Development
    Msrb1-/- mice (made with Bruce4 ES cells which are of uncertain origin) were crossed with Msra-/- (identical to MMRRC:12034, background B6;129X1) to make Msra-/- x Msrb1-/- mice. Zygotes collected from the double-KOs were used for CRISPR. Targeting sites were selected on the first coding exon of the Msrb2 and Msrb3 genes. Together with Cas9 mRNA, sgRNAs were co-injected into zygotes collected from Msra-/- x Msrb1-/- mice. Embryos were transferred into pseudopregnant females and the pups carrying the mutant allele were identified by DNA sequencing. The founder for the Msrb3 knockout carried a 7-bp deletion (CCGAGAG). The founder for the Msrb2 knockout carried a fragment of approx. extra 200 bp that was inserted into the sgRNA cutting site. Subsequent crosses of (Msra-/- x Msrb1-/-) x (Msrb2+/-) and (Msra-/- x Msrb1-/-) x (Msrb3+/-) carried three mutations. The quadruples was then generated by mating the offspring. No additional backcrossings thereafter, necessitating STOCK designation due to the introduction of unknown genetic background components with Bruce4 cells and the presence of >2 inbred strains.

    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.

    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.

    Units Notes
    050539-UNC-EMBRYO Cryo-preserved embryos $1,404.00 / Non-Profit Aliquot Approximate quantity2 : 20-40 embryos / aliquot
    050539-UNC-SPERM Cryo-preserved spermatozoa $564.00 / Non-Profit Aliquot Approximate quantity3
    050539-UNC-RESUS Litter recovered from cryo-archive $2,914.00 / 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.
