Strain Description
Phenotype
No distinct phenotype.
Founder genetic background: B6D2F1
Strain genetic background: C57BL/6
Strain Development: fBZ heterozygous mice were bred with CaMKcre transgenic mice to generate mice heterozygous for both the fBZ allele and the CaMKcre transgene (fBZ/+;CaMKcre/+). The double heterozygous mice were mated with fBZ heterozygotes (fBZ/+;+/+) to obtain trkB conditional knockouts (fBZ/fBZ;CaMKcre/+) and their control animals. Animals heterozygous for both fBZ and CaMKcre were also used to analyze the pattern of Cre-mediated trkB knockout in the brain by using X-gal staining and b-galactosidase immunohistochemistry. The trkBlacZ allele was generated by crossing a cre transgene under the control of the b-actin promoter into fBZ/1 mice. Genotypes of mice were determined by PCR or Southern hybridization. Since transfer to MMRRC this strain has been further backcrossed to C57BL/6J to produce the congenic strain, B6.Cg-Tg(Camk2a-cre)1Lfr/Mmcd (MMRRC #15962), that is 99% C57BL/6J by micro satellite testing.

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@ucdavis.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:
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.
