Description

IL-36β (IL-1F8) signals through the IL-1Rrp2/IL-1RAcP receptor complex to drive NF-κB and MAPK activation, making it a key mediator in epithelial and immune cell inflammatory responses. This tag-free recombinant human IL-36β encompasses the full-length isoform 2 sequence (1–157 aa), and its biological activity has been confirmed by functional ELISA demonstrating that immobilized protein at 1 µg/mL binds recombinant human IL-1Rrp2 Fc chimera across a 0.15–5 µg/mL range, supporting use as a coating antigen for antibody validation, a positive control in cytokine detection assays, and a ligand in receptor-binding studies. Endotoxin levels below 1.0 EU/µg minimize LPS-driven artifacts, which provides a suitable basis for cell-based NF-κB reporter assays, immune cell activation experiments, and in vivo inflammation models where spurious innate immune signaling must be excluded. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, aligns with standards expected in quantitative signaling pathway studies and reference standard 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. Stimulates production of interleukin-6 and interleukin-8 in synovial fibrobasts, articular chondrocytes and mature adipocytes. Induces expression of a number of antimicrobial peptides including beta-defensins 4 and 103 as well as a number of matrix metalloproteases. 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.
