What Fos Conditional Knockout mouse models are available?

When Fos Conditional 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 Fos knockout embryonic lethal in mice?

It depends on background and allele design. Some Fos 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 Fos 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 Fos?

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.

Available Fos catalog models

10 Fos lines with QC documentation and technical support. Fos floxed mice use loxP flanked alleles for Cre dependent tissue specific knockout.

Fos-Flox
CKO
CKO
These mice carry loxP sites flanking exon 3-4 of Fos gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of Fos gene.

About Fos Mouse Model Types

A Fos knockout mouse has the Fos gene permanently inactivated, enabling loss of function studies. A Fos conditional knockout (floxed) mouse carries loxP sites flanking a critical exon of Fos, allowing Cre recombinase dependent deletion in specific tissues or at specific timepoints. Fos knockin models carry a precisely inserted sequence at the Fos locus, useful for reporter, tag, or humanization studies.
