IL-4 & IL-13 Reporter Cells
HEK-Blue™ IL-4/IL-13 Cells signaling pathway
HEK-Blue™ IL-4/IL-13 cells allow the detection of bioactive human interleukin-4 (IL-4) and human/murine IL-13 by monitoring the activation of the STAT-6 pathway. IL-4 and IL-13 are cytokines that play an important role in regulating inflammation and immune responses [1].
Cell line description:
HEK-Blue™ IL-4/IL-13 cells were generated by stable transfection of the human embryonic kidney HEK 293 cell line with the human STAT6 gene to obtain a fully active STAT6 pathway. The other genes of the pathway are naturally expressed in sufficient amounts. These cells were further transfected with a STAT6-inducible SEAP reporter gene.
HEK-Blue™ IL-4/IL-13 cells produce SEAP in response to IL-4 or IL-13 stimulation. The levels of STAT6-induced SEAP secreted in the supernatant can be easily determined using QUANTI-Blue™ Solution.
Stimulation of HEK-Blue™ IL-4/IL-13 cells with recombinant human IL-4 or IL-13 can be blocked by the neutralizing monoclonal hIL-4 and hIL-13-IgG antibodies, respectively.
Features of HEK-Blue™ IL-4/IL-13 cells:
- Fully functional IL-4/IL-13 signaling pathway
- Readily assessable SEAP reporter activity
- Functionally tested and guaranteed mycoplasma-free
Applications of HEK-Blue™ IL-4/IL-13 cells:
- Detection of human IL-4 and human/murine IL-13
- Screening of anti-IL-4, anti-IL4Rα, anti-IL-13, or anti-IL-13Rα1 antibodies
- Screening of JAK1 inhibitors

Details
The transcription factor STAT6 is activated primarily by two cytokines with overlapping biologic functions, IL-4 and IL-13 [1, 2].
It can also be activated by IFN-α in a cell-specific manner. In non-hematopoietic cells, IL-4 and IL-13 bind a receptor complex composed of the IL-4Ralpha and IL-13Ralpha1.
Upon ligand binding, the receptor complex activates the receptor-associated Janus kinases (JAK1 and Tyk2) leading to the recruitment of STAT6 and its phosphorylation.
Activated STAT6 forms homodimers that translocate to the nucleus where they bind the promoter of responsive genes inducing gene transcription.
In HEK-Blue™ IL-4/IL-13 cells stimulation with IL-4 or IL-13 activates the JAK/STAT6 pathway with the subsequent production of SEAP.
