Il1rn Knockout mouse models
Il1rn corresponds to human IL1RN and encodes the interleukin 1 receptor antagonist, a structural mimic of interleukin 1 that occupies IL-1R1 without recruiting the IL1RAP accessory chain, so no Myddosome forms and signaling is competitively silenced, the mechanism exploited therapeutically by anakinra. The locus produces a secreted isoform plus intracellular variants generated from alternative first exons, so deletion strategies must decide explicitly whether to remove all isoforms or only the secreted pool. Human biallelic loss causes deficiency of the interleukin 1 receptor antagonist, presenting with sterile multifocal osteomyelitis, periostitis, and pustulosis, and mouse nulls develop strain dependent arthritis and aortitis that is prominent on BALB/c and mild on C57BL/6, making background choice part of the experimental design rather than a detail. Use conditional nulls to test local buffering in skin, joint, or gut, isoform-specific knockins to separate secreted from intracellular function, and humanization when antagonist pharmacokinetics is the endpoint.
A conventional Il1rn knockout removes gene function in all cells that inherit the allele. It is a proven first pass for target validation when redundancy is low.
What Il1rn Knockout mouse models are available?
ingenious targeting laboratory offers 2 distinct Il1rn 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 Il1rn Knockout mouse models are available?
When Il1rn 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 Il1rn knockout embryonic lethal in mice?
It depends on background and allele design. Some Il1rn 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 Il1rn 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 Il1rn?
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.
