ABOUT
IL-10 responsive STAT3-SEAP reporter assay
HEK-Blue™ IL-10 cells are designed to monitor human IL-10-induced STAT3 stimulation or inhibition through SEAP detection. This colorimetric bioassay can be used for screening activatory molecules, such as engineered cytokines, or inhibitory molecules, such as neutralizing antibodies.
HEK-Blue™ IL-10 cells respond strongly to recombinant human IL-10, and to a lower extent to mouse (m)IL-10 (see figures). The reliable and consistent performance of HEK-Blue™ IL-10 cells makes them suitable for release assays of therapeutic molecules that inhibit IL-10 signaling, such as monoclonal antibodies.
Key features
- Readily assessable STAT3-inducible SEAP reporter activity
- Convenient readout using QUANTI-Blue™ Solution
- Response to human (h) IL-10 and, to a weaker extent, mouse (m) IL-10
- Stability guaranteed for 20 passages
Applications
- Therapeutic development
- Drug screening
- Release assay
Interleukin 10 (IL-10) is an anti-inflammatory cytokine with a crucial role in preventing inflammatory and autoimmune pathologies. While it is known for its immunosuppressive role in conditions such as inflammatory bowel disease and chronic infections, it also exhibits a surprising protective effect in cancer.
Note: A new clone is provided with an improved IL-10 response. The cat code has been changed accordingly (hkb-il10v2).

Details
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)1. 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 [1].
IL-10 also plays important homeostatic roles in non-immune cells, including neurons, adipocytes, and epithelial cells [1]. The manipulation of IL-10 production and signaling has thus become an attractive therapeutic strategy [2].
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) [1]. Importantly, STAT3 is also activated downstream of other cytokine receptors. How the cells trigger distinct and specific gene expression in response to cytokines signaling through the same transcription factor is not fully understood yet [1].
