Top1 is a well studied locus in mouse genetics. Allele design follows your phenotype goals and the published landscape for this gene.
2 existing alleles are indexed for Top1, including 1 conditional, including 1 knockout. Where the published set lacks the modification you need, ingenious targeting laboratory builds that allele with documented germline transmission.
Reporter alleles fuse a detectable marker to endogenous regulation so expression mirrors the native locus. ES cell characterization confirms signal location before germline transmission.
Quotes return in about 24 hours. Study ready cohorts often arrive near 26 weeks from contract start when breeding is direct.

FAQ
How long does a Top1 reporter project take?
Most custom reporter 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 Top1 knockout embryonic lethal in mice?
Lethality depends on genetic background and exact allele design. Some Top1 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 Top1 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.
How do I request a quote for Top1?
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.
