Genetic Alterations
Mice are homozygous for a 737-kb interval of chromosome 7 introgressed from C57BL/6J mice.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • Phenotype

    Homozygous: Mice have C57Bl/6ByJ-like pial collateral phenotype (abound number and larger diameter), its background mice BALB/cByJ have few or none pial collateral and smaller diameter.

    Strain Development
    The input strains to the congenic strains were BALB/cByJ (Bc; Jackson Laboratories Stock #001026), CXB3/ByJ (CXB3; #000353) and CXB4/ByJ (CXB4; #000354). CXB3 and CXB4 are recombinant inbred lines derived from BALB/cByJ and C57Bl/6ByJ (B6; #001139). The very different distributions of blocks of B6 and Bc genotypes in CXB3 and CXB4 have been mapped in detail (PMID:11737945). Of the 1078 genome-wide markers used in the mapping, 59.6% (CXB3) and 55.5% (CXB4) are the Bc allele. Congenic lines were generated using a speed congenics approach by backcrossing CXB3 and CXB4 to Bc mice to give F1 mice. Starting at the second backcross (F1 to Bc; N2 generation), PCR markers (SNPs, simple sequence length polymorphisms, and restriction fragment length polymorphisms) in the blocks of B6 genotype were used to select for mice that lost the B6 genotype outside of Candq1 but retained it within Candq1. Congenic lines from CXB3 and CXB4 were developed and maintained separately. 
    Suggested Control Mice
    Control B6 mice (C57BL/6J; #000664) were obtained from Jackson Laboratories as new stocks and phenotyped contemporaneously with the congenic lines.
    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.

    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.
