Sema7a Conditional Knockout mouse models
Sema7a conditional knockout mice carry a floxed allele so you delete function only where Cre recombinase is active. This design keeps the germline allele intact until you cross to a tissue specific Cre. It is often the first choice when a global knockout is lethal, when you need adult onset loss, or when regional redundancy masks a whole body phenotype.
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.

How long does a Sema7a conditional knockout project take?
Most custom conditional knockout projects run near twenty six weeks from contract activation to study ready animals when breeding is straightforward. Complex humanization or multi allele stacks can add time. We return detailed quotes within about twenty four hours so you can align cohort start dates with grant or IND milestones.
Is Sema7a knockout embryonic lethal in mice?
Lethality depends on genetic background and exact allele design. Some Sema7a 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 Sema7a animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a custom project with cryo or live dispatch options depending on cohort timing and geography.
