IL-12 Reporter Cells
HEK-Blue™ IL-12 Cells signaling pathway
HEK-Blue™ IL-12 cellswere engineered from the human embryonic kidney HEK 293 cell line to detect bioactive human and murine interleukin-12 (IL-12) by monitoring the activation of the JAK/STAT4 pathway.
IL-12 is a pro-inflammatory cytokine that regulates T-cell and natural killer-cell responses, as well as inducing the production of interferon-γ (IFN-γ) [1-3].

Cell line description:
HEK-Blue™ IL-12 cells were generated by stable transfection with the genes encoding for the human IL-12 receptor and IL-12 signaling pathway, as well as a STAT4-inducible secreted embryonic alkaline phosphatase (SEAP) reporter. The binding of IL-12 to its receptor triggers a signaling cascade leading to the activation of STAT4 and the subsequent production of SEAP. This can be readily assessed in the supernatant using QUANTI-Blue™ Solution, a SEAP detection reagent.
HEK-Blue™ IL-12 cells detect human and murine IL-12 (see figures).
Key features:
- Fully functional IL-12 signaling pathway
- Readily assessable STAT4-inducible SEAP reporter activity
Applications:
- Detection of human and murine IL-12
- Screening of anti-IL-12 and anti-IL-12R antibodies

Details
Interleukin 12 (IL-12), formerly known as cytotoxic lymphocyte maturation factor (CLMF) and natural killer cell stimulatory factor (NKSF), is primarily produced by dendritic cells and macrophages.
It promotes the development of Th1 responses and is a powerful inducer of interferon-gamma (IFN-γ) [1-3].
IL-12 exerts its biological effect following binding to the IL-12 receptor (IL-12R), which is a heterodimeric receptor composed of two subunits, IL-12R-β1 and IL-12R-β2.
The binding of IL-12 to its receptor triggers a signaling pathway involving TyK2 (tyrosine kinase 2), JAK2 (Janus kinase 2), and STAT4 (signal transducer and activator of transcription 4) which results in the production of IFN-γ.
In HEK-Blue™ IL-12 cells, activation of the STAT4 pathway with IL-12 leads to the production of SEAP.
