IL-10 Reporter Cells
HEK-Blue™ IL-10 cells were engineered from the human embryonic kidney HEK293 cell line to detect bioactive human interleukin 10 (IL-10) by monitoring the activation of the STAT3 pathway. These cells can also be used for screening anti-IL-10/10R antibodies.
IL-10 was originally depicted as a key mediator of anti-inflammatory responses. While the immunosuppressive action of IL-10 is illustrated by its genetic association to inflammatory bowel disease or its upregulated expression in chronic infections, an unanticipated IL-10 protective role has been reported in cancer . IL-10 also plays important homeostatic roles in non-immune cells, including neurons, adipocytes, and epithelial cells . The manipulation of IL-10 production and signaling has thus become an attractive therapeutic strategy .
Upon IL-10 binding, the IL-10Rα chain oligomerizes with the IL-10Rβ chain. This, in turn, allows the phosphorylation of JAK1 (Janus kinase 1) and TyK2 (Tyrosine kinase 2), and the subsequent activation of STAT3 (Signal transducer and activator of transcription 3) .
HEK-Blue™ IL-10 cells were generated by stable transfection of the human embryonic kidney HEK293 cell line with the genes encoding hIL-10R α and β chains, human STAT3, and the STAT3-inducible SEAP (secreted embryonic alkaline phosphatase) reporter. Binding of IL-10 to its receptor on the surface of HEK-Blue™ IL-10 cells triggers JAK1/STAT3 signaling and the subsequent production of SEAP. For your convenience, InvivoGen provides QUANTI‑Blue™ Solution, an easy and rapid means to detect and quantify SEAP activity in the cell culture supernatant.
FEATURES OF HEK-BLUE™ IL-10 CELLS:
- Fully functional IL-10 signaling pathway
- Readily assessable SEAP reporter activity
- Functionally tested
- Guaranteed mycoplasma-free
APPLICATIONS OF HEK-BLUE™ IL-10 CELLS:
- Detection of human IL-10 (0.3 - 30 ng/ml), and to a lesser extent mouse IL-10 (25 -1000 ng/ml)
- Screening of anti-IL-10/10R antibodies

Dose-response of HEK-Blue™ IL‑10 cells to recombinant hIL‑10. Cells were stimulated with increasing concentrations of recombinant human IL-10. After overnight incubation, the STAT3 response was determined using QUANTI-Blue™ Solution, a SEAP detection reagent, and reading the optical density (OD) at 630 nm. EC50 value is shown as mean ± SD
Response of HEK‑Blue™ IL ‑10 cells to a panel of cytokines.
Cells were stimulated with various human and murine recombinant cytokines:1 ng/ml of hIL-10, 30 ng/ml of mIL-10, 1 ng/ml of hIL-1β, hIL-2, hIL-6,hIL-12, hIL-22, hIL-23, hIFN-γ, hTNF-α, or 102 U/ml hIFN-α or -β. After overnight incubation, SEAP activity was assessed using QUANTI-Blue™Solution. The optical density (OD) at 630 nm is shown as mean ± SEM.
Dose‑dependent inhibition of HEK‑Blue™ IL ‑10 cellular response using a neutralizing antibody against the hIL‑10 receptor (hIL10R).
The anti-hIL10R antibody was incubated with the cells for 30 minutes prior to the addition of hIL-10 (0.5 ng/ml). After overnight incubation, SEAP activity in the cell culture supernatant was assessed using QUANTI-Blue™ Solution. Data represent % of maximal reporter activity without the anti-hIL10R antibody

Interleukin 10 (IL-10), is the founding member of the IL-10 cytokine family, which comprises IL-10, IL-19, IL-20, IL-22, IL-24, IL-26, IL-28A (IFN-λ2), IL-28B (IFN-λ3), and IL-29 (IFN-λ1) . HEK-Blue™ IL-10 cells were generated by stable transfection of the human embryonic kidney HEK293 cell line with the genes encoding hIL-10R α and β chains, human STAT3, and the SEAP (secreted embryonic alkaline phosphatase) reporter gene. The reporter gene is placed under the control of the IFN-β minimal promoter fused to AP1- and STAT3-binding sites. Because STAT3 is also implicated in the signaling of cytokines that do not belong to the IL-10 family, such as IFN-α/β and IL-6, HEK-Blue™ IL-10 cells are knockout for the expression of hIFNAR2 and hIL-6R.
HEK-Blue™ IL-10 cells were tested negative for the detection of hIL-1β, hIL-2, hIL-6, hIL-12, hIL-22, hIL-23, hINF-α, hIFN-β, hIFN-γ, and hTNF-α.
