Gene Information

Allele Symbol: Dbhtm1(Dbh-FLPo)Xxx (Mus musculus (mouse))
Alteration at locus: Endonuclease-mediated
Monarch Initiative (Disease and Phenotype Associations):
Gene Symbol: Dbh (Mus musculus (mouse))
Name: dopamine beta hydroxylase
Chromosome: 2
Alteration at locus: Endonuclease-mediated
Monarch Initiative (Disease and Phenotype Associations): MGI:94864
Genetic Alterations
FlpO recombinase was knocked in to the Dbh start codon, with deletion of 106 bps in first exon. The transgene was inserted into AB2.2 ES cells by electroporation.
ES Cell Line
AB2.2 derived from 129S7/SvEvBrd-Hprtb-m2

Homozygous: Embryonically lethal

Hemizygous: No observed phenotype

Strain Development
Made in AB2.2 derived from 129S7/SvEvBrd-Hprtb-m2 ES cells, then injected into C57BL/6J. Mice were crossed to ACTB-cre strain (B6N.FVB-Tmem163<Tg(ACTB-cre)2Mrt>/CjDswJ - JAX Strain #019099, which is >N14 to C57BL/6N), then bred 3 generations to C57BL/6J.

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.

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.

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 $) Units Notes
041577-UCD-EMBRYO Cryo-preserved embryos $1,038.00 / Non-Profit Aliquot Approximate quantity3 : 20-40 embryos / aliquot
041577-UCD-SPERM Cryo-preserved spermatozoa $546.25 / Non-Profit Aliquot Approximate quantity2
041577-UCD-RESUS Litter recovered from cryo-archive $3,033.00 / Non-Profit Litter Recovered litter1; additional fees for any special requests.

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.
