Rxra Conditional Knockout mouse models
Rxra, the mouse ortholog of human RXRA, encodes retinoid X receptor alpha, the obligate heterodimer partner for RAR, PPAR, LXR, FXR, VDR, and NR4A receptors, which makes its deletion a simultaneous collapse of multiple nuclear receptor axes rather than a single pathway lesion. As the permissive partner it contributes DNA binding at direct repeats and coregulator recruitment, and it is the pharmacological target of rexinoids such as bexarotene. Germline nulls die in mid to late gestation with myocardial thinning, ventricular hypoplasia, and placental defects, so conditional alleles with Alb-Cre, K14-Cre, LysM-Cre, or Mx1-Cre are essential to reach adult metabolic, epidermal, and myeloid endpoints. Point knockins that selectively disable ligand binding or the heterodimer interface separate structural partnering from ligand-dependent activation, and humanized ligand-binding domains support rexinoid pharmacology. Rxrb and Rxrg substitute in several tissues, so compound conditional deletion is often required before assigning a phenotype to Rxra.
Tissue restricted knockout of Rxra keeps wild type function everywhere else. Breeding is often more robust, and the setup mirrors patient biology where mutations arise in a subset of cells.

| These mice carry loxP sites flanking exon3-4 of Rxra gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of Rxra gene. | |||||
Why this approach
Conditional knockout focuses the experiment on your target tissue while the rest of the animal keeps a wild type allele. That pattern mirrors somatic mutation in patients and avoids systemic compensation that can erase subtle phenotypes. It is often preferred when a germline null is lethal, weak, or confounded by developmental rescue.

FAQ
What Rxra Conditional Knockout mouse models are available?
When Rxra Conditional Knockout lines are in catalog, we ship from inventory. If your configuration is not listed, we design the allele to order. Common paths include conditional knockout, constitutive knockout, humanized, knockin, and transgenic options, with documented germline transmission and United States QC.
Is Rxra knockout embryonic lethal in mice?
It depends on background and allele design. Some Rxra germline knockouts are viable. Others need conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null before you commit.
Which Cre driver is best for experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak. We map your organ and cell type to a short list of proven Cre lines, then talk through reporter crosses and controls. We favor drivers with strong community validation for your tissue.
Do you ship live Rxra animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a generation project with cryo or live dispatch depending on cohort timing and geography.
How do I request a quote for Rxra?
Use the catalog inquire buttons or the request quote form. Include your allele goal, Cre plan if any, strain background, and cohort size. A PhD led team responds with pricing, milestones, and the fastest path to experimental animals.
