Notch3 Knockin mouse models
Notch3, the mouse ortholog of human NOTCH3, encodes a receptor with a shorter extracellular region than Notch1 and expression concentrated in vascular smooth muscle and pericytes, where canonical Adam10 and gamma-secretase processing releases an intracellular domain that acts through Rbpj and Maml to drive Heyl and mural cell maturation. Its disease logic is distinctive and not simple loss of function: CADASIL arises from cysteine-altering substitutions within EGF repeats that promote ectodomain multimerization and granular osmiophilic material deposition in arteriolar walls, a proteinopathy mechanism, whereas PEST-truncating alleles that stabilize signaling cause lateral meningocele syndrome. Homozygous nulls are viable with immature, poorly differentiated arterial smooth muscle and impaired myogenic responses, so germline alleles are usable, but the informative CADASIL model requires a patient-matched cysteine substitution knockin, ideally in a humanized EGF repeat context, rather than deletion. Notch1 contributes to mural cell biology, so compound alleles and a smooth muscle driver refine interpretation.
Notch3 knockin models place a defined sequence at the endogenous locus. Expression stays under native regulation, which matters for reporters, tags, and precise allele swaps.
What Notch3 Knockin mouse models are available?
ingenious targeting laboratory offers 2 distinct Notch3 knockin catalog mouse models. Researchers can order pre-developed catalog lines or request a custom mouse model, including humanized, knockin, and transgenic variations with verified germline transmission.
Why this approach
Knockin and humanized formats keep 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.

FAQ
What Notch3 Knockin mouse models are available?
When Notch3 Knockin lines are in catalog, we ship from inventory. If your configuration is not listed, we design the allele to order. Common paths include conditional knockout, constitutive knockout, humanized, knockin, and transgenic options, with documented germline transmission and United States QC.
Is Notch3 knockout embryonic lethal in mice?
It depends on background and allele design. Some Notch3 germline knockouts are viable. Others need conditional alleles or mixed backgrounds. We review publications and our own experience, then recommend floxed versus null before you commit.
Which Cre driver is best for experiments?
Driver choice depends on onset timing, recombination efficiency, and known leak. We map your organ and cell type to a short list of proven Cre lines, then talk through reporter crosses and controls. We favor drivers with strong community validation for your tissue.
Do you ship live Notch3 animals?
When catalog lines are live, we ship with health certificates and QC documentation. If your exact combo is not listed, we quote a generation project with cryo or live dispatch depending on cohort timing and geography.
How do I request a quote for Notch3?
Use the catalog inquire buttons or the request quote form. Include 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.
