描述（Description）
The Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell was engineered to not only express STAT3 signaling response element, but also express the receptors full length human IL-22 R alpha 1 (Gene ID: 58985) and IL-10 R beta (Gene ID: 3588). When stimulated with human IL-22 protein, receptor-mediated signaling can drive STAT3-mediated luminescence. Neutralization of biological effect of human IL-22 protein by corresponding antibody results in a decrease in luminescence.
应用说明（Application）
• Screen for neutralizing antibodies blocking the stimulation of human IL-22 protein.
• Bioactivity detection of human IL-22 fusion protein.

Receptor Assay
Co-expression analysis of human IL-22 R alpha 1 and IL-10 R beta on Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell or negative control cell using anti-human IL-22 antibody followed by staining with PE anti-human IgG Fc antibody and APC-labeled anti-IL-10 R beta antibody.
Protocol
Application
Inhibition of human IL-22 protein-induced reporter activity by anti-human IL-22 neutralizing antibody.
The Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell was incubated with serial dilutions of antibodies in the presence of human IL-22 protein (Cat.No.IL2-H524a) with a final concentration of 0.0005 μg/mL. The EC50 of anti-human IL-22 neutralizing antibody is approximately 0.004567 μg/mL.
Protocol
Signaling Bioassay
Response to human IL-22 protein (RLU).
The Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-22 protein (Cat.No.IL2-H524a). The EC50 was approximately 0.0003194 μg/mL.
Protocol
Response to human IL-22 protein (FOLD).
The Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-22 protein (Cat.No.IL2-H524a). The max induction fold was approximately 111.91.
Protocol
Passage Stability
Passage stability analysis by Signaling Bioassay.
The continuously growing Human IL-22 R alpha 1/IL-10 R beta (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of IL-22 protein. IL-22 protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 5-22.

背景（Background）
The receptor for IL-22, a heterodimeric complex of IL-22RA1 and IL-10RB, binds IL-22, activating signaling pathways that induce genes important for cellular proliferation, inhibition of apoptosis and tissue specific genes, that can include antimicrobial proteins and mucins.
