Il1b Knockout mouse models
Interleukin 1 beta, encoded by the mouse ortholog of human IL1B, is transcribed as an inactive 31 kDa precursor whose maturation requires cleavage at Asp116 by caspase-1 assembled on NLRP3, NLRC4, AIM2, or pyrin inflammasomes, with caspase-8 and neutrophil elastase providing inflammasome independent routes, and export depends on gasdermin D pores rather than the classical secretory pathway. Mature ligand engages IL-1R1 with IL1RAP, recruits MyD88 and IRAK4, and drives NF-kB dependent fever, neutrophil recruitment, interleukin 6 induction, and Th17 support, the axis blocked clinically by canakinumab and anakinra and hyperactivated in cryopyrin associated periodic syndromes. Allele forks are unusually clean: conditional null for requirement, cleavage-resistant knockin to separate transcription from processing, reporter alleles to time inflammasome activity in vivo, and humanization for antibody pharmacology. Because interleukin 1 alpha signals through the same receptor, attribute phenotypes with Il1a comparison rather than assuming Il1r1 readouts reflect interleukin 1 beta alone.
Il1b null animals are straightforward to genotype and phenotype when survival is acceptable. They remain a standard background for pharmacology, biomarker, and rescue studies.
What Il1b Knockout mouse models are available?
ingenious targeting laboratory offers 2 distinct Il1b 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 Il1b Knockout mouse models are available?
When Il1b 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 Il1b knockout embryonic lethal in mice?
It depends on background and allele design. Some Il1b 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 Il1b 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 Il1b?
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.
