Product Description | Recombinant HEK293 cells stably express human interleukin 4 receptor (IL - 4R) on the surface. The luciferase reporter gene was inserted into the genome of the cell under the control of STAT6 - RE. The cytokine samples (IL - 4 and IL - 13) can activate the receptor and transmit this signal to the downstream signaling pathways. The surface expression of IL - 4R is validated by luminescence analysis. This stable cell line product is designed for In Vitro cell - based functional assays to determine the bioactivity of IL - 4 and IL - 13. |

Figure 1. IL-4-induced luciferase expression in HEK293/STAT6-RE-Luc cells. After stimulation by agonist IL-4 (Cat. No. Z02925, Genscript) for 6 hours, the cells are determined with Fire-Lumi? Luciferase Assay System (Cat. No. L00877C-100, Genscript) and the relative luminescence units (RLU) were recorded by plate reader (Pherastar, BMG). The RLU were plotted against the log of the cumulative doses of IL-4 (Mean ± SEM, n = 3). The EC50 of IL-4 on this cell was 28.72 ng/ml.

Figure 2. IL-13-induced luciferase expression in HEK293/STAT6-RE-Luc cells. After stimulation by agonist IL-13 (Cat. No. Z03020, Genscript) for 6 hours, the cells are determined with Fire-Lumi? Luciferase Assay System (Cat. No. L00877C-100, Genscript) and the relative luminescence units (RLU) were recorded by plate reader (Pherastar, BMG). The RLU were plotted against the log of the cumulative doses of IL-13 (Mean ± SEM, n = 3). The EC50 of IL-13 on this cell was 29.27 ng/ml.
Notes:
EC50 value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom) / (1+10^((LogEC50-X)*Hill Slope))
X is the logarithm of concentration. Y is the response.
Y is RLU and starts at Bottom and goes to Top along a sigmoid curve. ?
