Genetic Alterations
Exons 17 and 18 of the Dnai1 gene are floxed. The frt flanked neo cassette used for selection purposes was removed by flp mediated recombination leaving a single frt site.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    129Sv derived from 129S2/SvPas
    Phenotype

    Homozygous floxed mice are phenotypically normal.

    Conditional phenotype: Deletion of the Dnai1 gene via Cre-mediated recombination results in a Primary Ciliary Dyskinesia (PCD) mouse model with defective cilia. The cilia become immotile and mucociliary clearance is impaired or absent. Mice develop chronic rhinosinusitis, similar to the human condition.

    Strain Development
    The Dnai1flox/flox strain was generated via homologous recombination in embryonic stem cells (ESC). Briefly, high-fidelity, long-distance PCR was used to amplify fragments of mouse genomic DNA surrounding exons 17 and 18 of Dnaic1. The fragments were cloned into a plasmid containing the flanking loxP sites and selectable markers. The plasmid construct was electroporated into 129Sv ESCs derived from 129S2/SvPas, and neomycin-resistant clones were screened by Southern analysis. The neomycin cassette was flanked by FRT sites and was removed using FLP recombinase. The selected ESCs were injected into mouse blastocysts and transferred to pseudo-pregnant female mice to allow for development of transgenic mice carrying the targeted Dnaic1 gene. Mice were genotyped by PCR of genomic DNA using primers that flank the targeted region. Dnaic1flox/flox animals were maintained on a mixed background C57BL/6 and 129 background.

    Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain's tissue samples taken when archived by or ordered from the assigned MMRRC Center.

    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.
