Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

5-10 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

IL-36α (IL-1F6) drives pro-inflammatory signaling through the IL-36 receptor, activating NF-κB and MAPK pathways that are central to epithelial and immune cell responses in murine models of skin and lung inflammation. This tag-free recombinant mouse IL-36α, encompassing the full mature sequence (8–160 aa), demonstrates an ED50 of less than 25 ng/mL in an IL-6 secretion assay using NIH/3T3 cells, corresponding to a specific activity exceeding 4.0 × 10⁴ IU/mg — providing a reliable reference for cell-based functional assays, NF-κB/MAPK signaling studies, and use as a quantitative standard in cytokine detection platforms. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in sensitive immune cell activation experiments and in vivo inflammatory models where confounding innate immune stimulation must be controlled. Purity exceeding 95% by SDS-PAGE, combined with this endotoxin profile, also satisfies the criteria typical for antibody development workflows including immunization, ELISA coating, and positive control applications.

Target Background

Function

Cytokine that binds to and signals through the IL1RL2/IL-36R receptor which in turn activates NF-kappa-B and MAPK signaling pathways in target cells linked to a pro-inflammatory response. Part of the IL-36 signaling system that is thought to be present in epithelial barriers and to take part in local inflammatory response; similar to the IL-1 system with which it shares the coreceptor IL1RAP. Seems to be involved in skin inflammatory response by acting on keratinocytes, dendritic cells and indirectly on T-cells to drive tissue infiltration, cell maturation and cell proliferation. Induces the production of proinflammatory cytokines, including IL-12, Il-1 beta, IL-6, TNF-alpha and IL-23 in bone marrow-derived dendritic cells (BMDCs). Involved in dendritic cell maturation by stimulating the surface expression of CD80, CD86 and MHC class II. Induces the production of IFN-gamma, IL-4 and IL-17 by cultured CD4(+) T-cells and splenocytes. May play a role in proinflammatory effects in the lung: induces the expression of CXCL1 and CXCL2 in the lung, and the expression of TNF-alpha, IL-36c, IL-1A, IL-1B, CXCL1 and CXCL2 in isolated splenic CD11c(+) alveolar macrophages. May be involved in T-cell maturation by stimulating the surface expression of CD40 and modestly CD80 and CD86 in splenic CD11c(+) cells. May be involved in CD4(+) T-cell proliferation. Induces NF-kappa B activation in macrophages.
