Il4 Knockin mouse models
Il4 is the mouse ortholog of human IL4 and encodes the initiating type 2 cytokine, signaling through the type I receptor of IL-4Ralpha with the common gamma chain on lymphocytes and the type II receptor of IL-4Ralpha with IL-13Ralpha1 on myeloid and stromal cells, converging on STAT6 to induce GATA3, immunoglobulin E class switching, and alternative macrophage activation. Its locus lies adjacent to Il13 and Il5 under shared conserved noncoding regulatory elements, so cassette placement can perturb neighbors and generate phenotypes mistakenly attributed to interleukin 4 alone. Because interleukin 4 and interleukin 13 share IL-4Ralpha and STAT6, single nulls give partial results and compound Il4 with Il13 or Il4ra deletion is required for full type 2 collapse. Bicistronic fluorophore reporter knockins mark competent producers without perturbation, while humanization is the appropriate allele for dupilumab-class receptor blockade, and conditional deletion with Cd4-Cre or ILC2 restricted drivers assigns the cellular source.
Targeting Il4 preserves positional context compared with viral or BAC approaches. That helps when you quantify expression or map chromatin.
What Il4 Knockin mouse models are available?
ingenious targeting laboratory offers 2 distinct Il4 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 Il4 Knockin mouse models are available?
When Il4 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 Il4 knockout embryonic lethal in mice?
It depends on background and allele design. Some Il4 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 Il4 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 Il4?
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.
