Human IL-21 R/CD132 (Luc) HEK293 Reporter Cell

For research use only.

描述(Description)

The Human IL-21 R/CD132 (Luc) HEK293 Reporter Cell was engineered to not only express STAT3 signaling response element, but also express the receptors full length human IL-21 R (Gene ID:50615) and CD132 (Gene ID:3561). When stimulated with human IL-21 protein, the IL-21/ IL-21 R interaction drives STAT3-mediated luminescence. Inhibition of IL-21 binding to IL-21 R by either anti-IL-21 or anti-IL-21 R antibodies results in a decrease in luminescence.

应用说明(Application)

• Screen for anti-human IL-21 or anti-human IL-21 R neutralizing antibody.

Receptor Assay

IL-21 R FACS

Co-expression analysis of human IL-21 R and CD132 on Human IL-21 R/CD132 (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human IL-21 R/CD132 (Luc) HEK293 Reporter Cell or negative control cell using BV421-labeled anti-IL-21 R antibody and PE-labeled anti-CD132 antibody.

Protocol

 

Application

IL-21 R APPLICATION

Inhibition of human IL-21 protein-induced reporter activity by anti-human IL-21 neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IL-21 protein (Cat. No. IL1-H5213) with a final concentration of 0.01 μg/mL. The EC50 of anti-human IL-21 neutralizing antibody is approximately 0.1545 μg/mL.

Protocol

 

Signaling Bioassay

IL-21 R SIGNALING

Response to human IL-21 protein (RLU).
The Human IL-21 R /CD132 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-21 protein (Cat. No. IL1-H5213). The EC50 was approximately 0.0068 μg/mL.

Protocol

IL-21 R SIGNALING

Response to human IL-21 protein (Fold).
The Human IL-21 R /CD132 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-21 protein (Cat. No. IL1-H5213). The max induction fold was approximately 46.1.

Protocol

 

Passage Stability

IL-21 R PASSAGE

Passage stability analysis by Signaling Bioassay.
The continuously growing Human IL-21 R/CD132 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IL-21 protein. Human IL-21 protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 7-21.

背景(Background)

Interleukin-21 receptor (IL21R) is also known as CD antigen CD360, Novel interleukin receptor (NILR), is a receptor for interleukin-21 and belongs to the type I cytokine receptor family or type 4 subfamily. IL21R contains two fibronectin type-III domains. IL21R is selectively expressed in lymphoid tissues and most highly expressed in thymus and spleen. IL21R transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells.
