Cfd Knockout mouse models
Complement factor D, also called adipsin, is encoded by mouse Cfd, ortholog of human CFD, and constitutes the rate-limiting protease of the alternative pathway. Factor D is unique among complement proteases in circulating as a mature enzyme rather than a zymogen, held in a self-inhibited conformation by a distorted active site and a blocking self-inhibitory loop that is relieved only upon docking to the exosite presented by factor B once factor B has engaged C3b, an elegant substrate-induced activation that prevents fluid phase proteolysis. It is secreted largely by adipocytes, linking metabolic tissue to complement amplification and insulin secretion biology. Human deficiency causes recurrent Neisseria infection, and mouse nulls lack alternative pathway activity while retaining classical function, with no paralog to compensate. Choose the null or an adipocyte-conditional allele to test tissue source and metabolic crosstalk, and humanized knockins when danicopan class molecules exploiting the self-inhibited pocket are the endpoint.
Global Cfd deletion answers broad mechanism questions quickly. If timing or site matters, conditional alleles are a natural next step after the null is characterized.
What Cfd Knockout mouse models are available?
ingenious targeting laboratory offers 2 distinct Cfd knockout 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
A conventional knockout answers whether the gene is required broadly. When your target tissue is the organ of interest, a global null can still be informative if viability is acceptable and you want the simplest genotype. If the null is harsh, a floxed allele with a regional Cre is the safer long term platform.

FAQ
What Cfd Knockout mouse models are available?
When Cfd Knockout 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 Cfd knockout embryonic lethal in mice?
It depends on background and allele design. Some Cfd 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 Cfd 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 Cfd?
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.
