Description

IL-36γ is a key IL-1 family cytokine that drives NF-κB and MAPK signaling through IL-36R, making it central to epithelial and immune cell inflammatory responses. This tag-free recombinant human IL-36G, encompassing the full mature sequence (18–169 aa), demonstrates strong signaling potency with an ED50 below 10 ng/mL in an IL-8 secretion assay using human preadipocytes, corresponding to a specific activity exceeding 1 × 10⁵ IU/mg — a level that supports use in cell-based activation assays, NF-κB/MAPK pathway dissection, and as a reference standard in cytokine detection platforms. Endotoxin levels below 1.0 EU/μg minimize the risk of LPS-driven artifacts in sensitive immune cell experiments, including primary cell stimulation assays and in vivo inflammation models. Purity above 95% by SDS-PAGE, combined with this endotoxin profile, provides a suitable basis for antibody development workflows such as immunogen preparation, ELISA coating, and Western blot positive controls.

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. 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; also stimulates its own expression and that of the prototypic cutaneous proinflammatory parameters TNF-alpha, S100A7/psoriasin and inducible NOS. May play a role in proinflammatory responses during particular neutrophilic airway inflammation: activates mitogen-activated protein kinases and NF-kappa B in primary lung fibroblasts, and stimulates the expression of IL-8 and CXCL3 and Th17 chemokine CCL20 in lung fibroblasts. May be involved in the innate immune response to fungal pathogens, such as Aspergillus fumigatus.
