Genotype Determination

Not specified
Phenotype
Homozygous: A targeting vector was designed to replace the 3' end of exon 9 of the solute carrier family 4 (anion exchanger), member 4 (Slc4a4 or Nbc1) gene with a neomycin resistance (neo) cassette. Homozygotes are viable, exhibit growth retardation, and die between 5 and 25 days of age. Nbc1 is expressed in the basolateral membrane of epithelial cells lining both the small and large intestine, in colonic crypts, as well as the kidney, eye, pancreas, and duodenum, and is required for anion secretion. Nbc1-/- mice exhibit severe metabolic and respiratory acidosis, growth retardation, reduced plasma Na+, hyperaldosteronism, splenomegaly, abnormal dentition, intestinal obstructions, and death before weaning. Intracellular pH (pHi) regulation is impaired and bioelectric colon measurements revealed increased amiloride-sensitive Na+ absorption. cAMPstimulated anion secretion is increased in proximal colon of these mutants compared to wildtype. These mice may be useful for studying pH homeostasis, bicarbonate absorption in the kidney, and intestinal and colonic anion secretion.

Heterozygous: Mice are viable, fertile, and normal in size. They exhibit normal growth, and are phenotypically similar to wildtype mice with the exception of a slight decrease in blood HCO3- levels.

Strain Development
A targeting vector was designed to replace the 3' end of exon 9 of the solute carrier family 4 (anion exchanger), member 4 (Slc4a4 or Nbc1) gene with a neomycin resistance (neo) cassette. The construct was electroporated into 129S6/SvEvTac-derived embryonic stem (ES) cells and correctly targeted ES cells were injected into blastocysts. The resulting chimeric males were bred to Black Swiss females. This strain was maintained on a 129/Black Swiss background. Upon arrival at The Jackson Laboratory, mice were bred to 129S1/SvImJ inbred mice for at least one generation to establish the colony.

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 csmmrrc@jax.org. Older strains may not have this information.

Colony and Husbandry Information

When maintaining a live colony, heterozygous mice may be bred to wildtype mice from the colony. Homozygous animals are smaller and die between 5 and 25 days of age due to malnutrition and brittle teeth.

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.

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 csmmrrc@jax.org.

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 csmmrrc@jax.org 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.

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.
