R26 Knockin mouse models

Knockin designs at R26 support head to head comparisons between wild type and modified alleles because regulatory DNA stays in place.

How long does a R26 knockin project take?

Most custom knockin 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 R26 knockout embryonic lethal in mice?

Lethality depends on genetic background and exact allele design. Some R26 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 R26 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 R26?

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.
