Notch1 Knockin mouse models
Notch1, the mouse ortholog of human NOTCH1, encodes a single-pass receptor whose EGF-like repeats 11 and 12 bind Dll and Jag ligands, with Fringe-mediated O-fucose elongation tuning ligand preference; furin cleavage at S1 generates a heterodimer held together by the negative regulatory region, and mechanical pulling by an endocytosing ligand exposes S2 for Adam10, after which gamma-secretase cleaves at S3 to release the intracellular domain, which enters the nucleus, displaces corepressors from Rbpj, and recruits Maml to activate Hes and Myc, until a carboxy-terminal PEST degron directs Fbxw7-dependent turnover. Human T-cell leukemia mutations cluster in the negative regulatory region and PEST, while loss underlies Adams-Oliver syndrome and bicuspid aortic valve. Homozygous nulls die near E10.5 with somitogenesis and vascular defects, so conditional alleles are standard, and Lox-Stop-Lox intracellular domain knockins, patient-matched PEST truncations, and humanized negative regulatory regions for antibody testing answer separate questions. Notch2 partially compensates, so plan compound genetics.
Targeting Notch1 preserves positional context compared with viral or BAC approaches. That helps when you quantify expression or map chromatin.

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 Notch1 Knockin mouse models are available?
When Notch1 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 Notch1 knockout embryonic lethal in mice?
It depends on background and allele design. Some Notch1 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 Notch1 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 Notch1?
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.
