Sema5a Conditional Knockout mouse models
Conditional deletion of Sema5a limits genetic change to the lineage you choose. That precision matters for oncology, immunology, and metabolic work where systemic loss would confound interpretation. After you confirm your Cre specificity, crossing to Sema5a floxed stock yields interpretable cohorts.
Catalog table
Conditional knockout keeps your target tissue 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.
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.

FAQ
Is Sema5a knockout embryonic lethal in mice?
Lethality depends on genetic background and exact allele design. Some Sema5a 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 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. We prioritize drivers with strong community validation for your tissue.
Do you ship live Sema5a 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 Sema5a?
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.
