描述（Description）
The Human TSLP R (Luc) HEK293 Reporter Cell was engineered to not only express STAT5 signaling response element, but also express the receptors full length human TSLP R (Uniprot: Q9HC73-1) and IL-7 R alpha (Uniprot: P16871-1). When stimulated with human TSLP protein, the TSLP/TSLP R interaction drives STAT5-mediated luminescence. Inhibition of TSLP binding to TSLP R by either anti-TSLP or anti-TSLP R antibodies results in a decrease in luminescence.

Receptor Assay
Co-expression analysis of human TSLP R and IL-7 R alpha on Human TSLP R (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human TSLP R (Luc) HEK293 Reporter Cell or negative control cell using PE-labeled anti-TSLP R antibody and FITC-labeled anti-IL-7 R alpha antibody.
Protocol
Application
Inhibition of human TSLP protein-induced reporter activity by anti-human TSLP neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human TSLP protein (Cat. No. TSP-H52Hb) with a final concentration of 0.3 μg/mL. The EC50 of anti-human TSLP neutralizing antibody is approximately 0.55 μg/mL.
Protocol
Signaling Bioassay
Response to human TSLP protein (RLU).
The Human TSLP R (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human TSLP protein (Cat. No. TSP-H52Hb). The EC50 was approximately 0.1392 μg/mL.
Protocol
Response to human TSLP protein (Fold).
The Human TSLP R (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human TSLP protein (Cat. No. TSP-H52Hb). The max induction fold was approximately 45.15
Protocol
Passage Stability
Passage stability analysis by Signaling Bioassay.
The continuously growing Human TSLP R (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human TSLP protein. Human TSLP protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 10-26.

背景（Background）
Thymic stromal lymphopoietin (TSLP) is a pleiotropic cytokine and takes multi-functions via binding to a high-affinity heteromeric complex composed of thymic stromal lymphopoietin receptor (TSLPR) chain and IL-7Rα. The receptor complex on cells co-expressing TSLPR and IL-7Rα activated downstream genes expression and initiate proinflammatory signaling. TSLP involved in a variety of allergic diseases (e.g., atopic dermatitis, bronchial asthma). Further investigation indicated that TSLP is also involved in chronic inflammatory (i.e., chronic obstructive pulmonary disease and celiac disease) and autoimmune (e.g., psoriasis, rheumatoid arthritis) disorders and several cancers.
