Flt1 Knockin mouse models
Flt1, ortholog of human FLT1, encodes VEGFR1, a receptor tyrosine kinase whose seven immunoglobulin-like extracellular domains bind VEGFA with roughly an order of magnitude higher affinity than VEGFR2 while its kinase domain signals only weakly, making it primarily a decoy that restrains VEGF availability. Alternative processing yields soluble sFLT1, which sequesters circulating VEGF and placental growth factor and is a central mediator of preeclampsia. The genetics resolve this elegantly and should guide design: null embryos die from endothelial overgrowth and disorganized vessels, whereas kinase-dead knockin animals are viable and largely normal, demonstrating that ligand sequestration rather than catalysis is the essential function. Conditional deletion therefore addresses tissue-specific VEGF buffering, isoform-selective alleles isolate the soluble species, and humanized ectodomains support testing of VEGF traps such as aflibercept. Read out vascular density and branching, permeability, proteinuria and blood pressure in pregnancy models, and free VEGF levels.
Flt1 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 Flt1 Knockin mouse models are available?
ingenious targeting laboratory offers 2 distinct Flt1 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 Flt1 Knockin mouse models are available?
When Flt1 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 Flt1 knockout embryonic lethal in mice?
It depends on background and allele design. Some Flt1 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 Flt1 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 Flt1?
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.
