    Strain Description

    Phenotype
    The mutation prevents phosphorylation of the affected residue in the encoded peptide. To be clear, this strain does not form a functional Grk1 protein and does not have Rd8 retinal degeneration present in C57BL/6N mice.

    Strain Development
    Embryonic stem cells from 129X1/SvJ mice were used to host the deletion and were injected into blastocysts of C57BL/6Crl mice. Chimeric mice were mated with C57BL/6Crl to produce the hemizygous knockout (RK+/−). Homozygous knockout (RK−/−) mice were produced by inbreeding of the RK+/− animals. Finally, the resulting line containing the S21A mutation was backcrossed to homozygosity and crossed at least twice into C57BL/6J mice to ensure the absence of the rd8 mutation.

    MMRRC Genetic QC

    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.

    Availability Level

    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.

    A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Carmen Melvin.

    Conditions of Distribution

    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.

    A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Carmen Melvin

    Fees

    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.

    MMRRC Item # Description Distribution Fee / Unit (US $)
    *Shipping & Handling not included*    		 Units Notes
    071689-UNC-RESUS Litter recovered from cryo-archive $3,088.00 / $5,126.00
    Non-Profit / For-Profit    		 Litter Recovered litter4; additional fees for any special requests.
    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    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.
