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 signals through the IL-1Rrp2/IL-1RAcP receptor complex to activate NF-κB and MAPK pathways, making it a key driver of epithelial and immune cell inflammatory responses. This tag-free recombinant human IL-36A spans the full-length sequence (1–158 aa) and demonstrates confirmed receptor engagement, with immobilized protein at 1 µg/mL binding recombinant human IL-1Rrp2 Fc chimera across a 0.15–5 µg/mL range in functional ELISA — supporting its use as a coating antigen for antibody validation, a reference standard in cytokine detection assays, and a ligand in NF-κB or MAPK signaling pathway studies. Endotoxin levels below 1.0 EU/µg minimize LPS-driven artifacts that can confound keratinocyte activation assays, PBMC stimulation experiments, and in vivo inflammation models. Produced in *E. coli* at greater than 95% purity by SDS-PAGE, this preparation satisfies the quality criteria typical for cell-based functional assays and antibody development workflows.

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. In cultured keratinocytes induces the expression of macrophage, T-cell, and neutrophil chemokines, such as CCL3, CCL4, CCL5, CCL2, CCL17, CCL22, CL20, CCL5, CCL2, CCL17, CCL22, CXCL8, CCL20 and CXCL1, and the production of proinflammatory cytokines such as TNF-alpha, IL-8 and IL-6. In cultured monocytes upregulates expression of IL-1A, IL-1B and IL-6. In myeloid dendritic cells involved in cell maturation by upregulating surface expression of CD83, CD86 and HLA-DR. In monocyte-derived dendritic cells facilitates dendritic cell maturation and drives T-cell proliferation. May play a role in proinflammatory effects in the lung.
