Cd274 Knockin mouse models
Cd274 encodes PD L1, the ligand that engages PD1 on T cells. Models at this locus support tumor microenvironment studies, myeloid versus tumor expression split experiments, and combination regimens with chemotherapy or other checkpoints. Tissue selective deletion separates systemic biology from tumor intrinsic signaling. Humanized variants matter when programs need faithful binding to clinical antibodies.
An engineered Cd274 allele can introduce a human coding region, a point change, or a fluorescent reporter without random transgene integration noise.

Knockin and humanized formats preserve regulatory context at the endogenous locus. For your target tissue focused programs, that matters when expression timing, splice isoforms, or allele dosage drive biology. Random integration transgenics can still help, but targeted alleles usually give cleaner pharmacology readouts.
Knockin and humanized formats preserve regulatory context at the endogenous locus. For liver focused programs, that matters when expression timing, splice isoforms, or allele dosage drive biology. Random integration transgenics can still help, but targeted alleles usually give cleaner pharmacology readouts.

How long does a Cd274 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 Cd274 knockout embryonic lethal in mice?
Lethality depends on genetic background and exact allele design. Some Cd274 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 Cd274 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 Cd274?
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.
