IL-18 Reporter Cells

HEK-Blue™ IL-18 cells are designed to detect bioactive IL-18 by monitoring the activation of the NF-κB and AP-1 pathways. They were generated by stable transfection of HEK293 derived cells with the genes encoding IL-18R and IL-18RAP. 

In addition, the TNF-α and IL-1β responses have been blocked. Therefore, HEK-Blue™ IL-18 cells respond specifically to IL-18. These cells express an NF-κB/AP-1-inducible SEAP reporter gene.

Binding of IL-18 to the heterodimeric IL-18 receptor on the surface of these cells triggers a signaling cascade leading to the activation NF-κB and the subsequent production of SEAP.

Levels of SEAP in the supernatant can be easily determined with QUANTI-Blue™ Solution.


Response of HEK-Blue™ IL-18 cells to increasing concentrations of human and mouse recombinant IL-18. After a 24h incubation, the levels of SEAP were determined using QUANTI-Blue™ Solution, a SEAP detection reagent, and by reading the optical density (OD) at 630 nm.

HEK-Blue IL18 pathway

Interleukin-18 (IL-18) is a pro-inflammatory cytokine that causes a wide variety of biological effects associated with infection, inflammation and autoimmune processes.

It binds to an heterodimeric receptor consisting of IL-18R and IL-18 receptor accessory protein (IL18RAP) which then induces signaling pathways that involve MyD88, and TRAF-6 leading to the activation of NF-κB and AP-1.
