描述(Description)
The Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell was engineered to express STAT3 signaling response element, but also express the receptors full length human IL-31 RA (Gene ID: 133396) and OSMR (Gene ID: 9180). When stimulated with human IL-31 protein, the IL-31/IL-31 RA interaction drives STAT3-mediated luminescence. Neutralization of biological effect of human IL-31 protein by corresponding antibody results in a decrease in luminescence.

Receptor Assay

Co-expression analysis of human IL-31 RA and OSMR on Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell or negative control cell using PE-labeled anti-human IL-31 RA antibody and APC-labeled anti-human OSMR antibody.
Protocol
Application

Inhibition of human IL-31 protein-induced reporter activity by anti-human IL-31 RA neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IL-31 protein (Cat. No. IL1-H5247) with a final concentration of 0.001 μg/mL. The EC50 of anti-human IL-31 RA neutralizing antibody is approximately 0.609 μg/mL.
Protocol

Inhibition of human IL-31 protein-induced reporter activity by anti-human OSMR neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IL-31 protein (Cat. No. IL1-H5247) with a final concentration of 0.001 μg/mL. The EC50 of anti-human OSMR neutralizing antibody is approximately 0.727 μg/mL.
Protocol
Signaling Bioassay

Response to human IL-31 protein (RLU).
The Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-31 protein (Cat. No. IL1-H5247). The EC50 was approximately 0.0102 μg/mL.
Protocol

Response to human IL-31 protein (FOLD).
The Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-31 protein (Cat. No. IL1-H5247). The max induction fold was approximately 328.
Protocol
Passage Stability

Passage stability analysis by Signaling Bioassay.
The continuously growing Human IL-31 RA/OSMR (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-31 protein. Human IL-31 protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 9-20.

背景
Interleukin-31 receptor subunit alpha is a protein that in humans is encoded by the IL31RA gene, also known as IL-31 receptor subunit alpha, IL-31RA, GLM-R, Gp130-like receptor, CRL3, GPL. Oncostatin M receptor (OSMR) and IL31RA form the heterodimeric receptor through which IL31 signals. IL31RA is a strong activator of STAT3 and STAT5, whereas STAT1 is only marginally tyrosine-phosphorylated. dditionally, demonstrate Jak1 binding to GPL and its activation in heteromeric complexes with the OSMR beta but also in a homomeric receptor complex.
