Strain Name    :

B6.129S1-Chrna4tm3Lst/Mmmh

Stock Number :

030231-MU

Gene Information

Gene Details [Including genotyping protocols]

(provided by MGI)
Target: Chrna4tm3Lst
Name: targeted mutation 3, Henry Lester
Alteration at locus: Knock-In
Target: Chrna4
Name: cholinergic receptor, nicotinic, alpha polypeptide 4
Chromosome: 2
Alteration at locus: Knock-In

Genetic Alterations:
According to Donor's previous work, they found that the optimal insertion site for yellow fluorescent protein (YFP) was a BstEII site in the M3

Genotype Determination:

ES Cell Line: CJ7 derived from B6;129S1

Strain Description [Including phenotype, strain background, strain development and suggested control mice]

Phenotype

Homozygous phenotype: Alpha 4 Nicotinic receptors are flourescent due to the presence of fused YFP. The mice behave normally in every assay tested as compared to WT.

Heterozygous phenotype: Alpha4 Nicotinic receptor are flourescent due to the presence of fused YFP. Flourescence level is half that of Homozygotes.

  • no phenotypic analysis
    • no phenotypic analysis (MGI Ref ID J:123687)
      • no analysis; mice are used for quantitative studies of receptor expression regulation

Strain of Origin: Sv129

Strain genetic background: C57BL/6

Strain Development: All neo-deleted clones were sequenced to confirm the presence of the YFP mutation and deletion of the neo cassette. Karyotype analysis was used to verify normal chromosome number. Two neo-deleted Alpha 4YFP clones were injected into C57BL/6 blastocysts, and chimeras were established. Chimeras were mated with wild-type animals and germline transmission was established as assessed by PCR analysis of tail DNA and sequence analysis. The F1 generation was then baccrossed to C57 BL/6 to achieve N10 generation which was congenic.

Suggested Control Mice:

  • Wildtype littermates

Research Applications

  • Cell Biology
  • Developmental Biology
  • Models for Human Disease
  • Neurobiology

Colony and Husbandry Information

Special Considerations

None

Health Status Report

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@missouri.edu.

Order Request 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.

Conditions of Distribution [Including applicable technology transfer agreements]

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.

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.

1 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.

2 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.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
