Brca1 Conditional Knockout mouse — liver specific context
Brca1 maintains genome integrity through homologous recombination repair. Pathogenic variants raise breast and ovarian cancer risk, so mouse models support BRCA directed therapy development and synthetic lethality screens. Tissue restricted knockouts help isolate mammary biology without early embryonic complications that can complicate whole body loss. Humanized alleles are useful when antibodies are human epitope selective. Well chosen floxed lines shorten the path from genetics to pharmacology cohorts.
Tissue restricted knockout of Brca1 reduces off target stress compared with constitutive loss. You retain wild type Brca1 everywhere else, which improves breeding robustness and mirrors patient biology where mutations arise in a subset of cells. For liver work, plan Cre specificity, reporter crosses, and baseline phenotyping before you scale.
Catalog options
Conditional knockout keeps liver as the experimental theater while the rest of the animal retains 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.

Why this approach
Conditional knockout keeps neuron as the experimental theater while the rest of the animal retains 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
Is Brca1 knockout embryonic lethal in mice?
Lethality depends on genetic background and exact allele design. Some Brca1 germline knockouts are viable, others require conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null approaches before you commit.
Which Cre driver is best for liver specific focused experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak patterns. We map your organ and cell type to a short list of proven Cre lines, then discuss reporter crosses and controls. Your query highlights liver specific as a primary axis, which we treat as the starting point for driver selection.
Do you ship live Brca1 animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a model generation project with cryo or live dispatch options depending on cohort timing and geography.
How do I request a quote for Brca1?
Use the catalog inquire buttons or the request quote form with 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.
