| Product Description |
Recombinant HEK293 cells
stably express STAT6-RE-Luc and human interleukin 4
Receptor (IL-4R)
on the surface and activate the receptor to the downstream signaling pathways
upon the binding of IL-4 and IL-13. The surface expression of IL-4R
is validated by luminescence analysis. This stable cell line product is
designed for cell-based functional assays that measure binding affinity and
stability of antibody based biologics binding with IL-4 and IL-13. |
| Culture Properties |
Adherent |
| Stability |
Stable through more
than 15 passages with no significant changes in assay performance or expression
profile. |
| Size |
2 vials of frozen
cells (>1X106 per
vial in 1 ml) |
| Storage |
Store
cells in liquid nitrogen immediately upon receipt. Thaw and recover cells
within one year from the date received. |

Figure 1. Luminescence analysis of activation of STAT6-RE-Luc and IL-4R on HEK293 cells. The HEK293/STAT6-RE-Luc cells were stimulated by IL-4 (Cat. No. Z02925-50, Genscript). Fire-Lumi? Reagent (Cat. No. L00877C-1000, Genscript) was added and luminescence was measured by PHERAstar FSX. ?
Figure 2. Luminescence analysis of activation of STAT6-RE-Luc and IL-13R on HEK293 cells. The HEK293/STAT6-RE-Luc cells were stimulated by IL-13 (Cat. No. Z03020-50, Genscript). Fire-Lumi? Reagent (Cat. No. L00877C-1000, Genscript) was used and luminescence measured by PHERAstar FSX.
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.
