Human IL-4 R alpha/IL-13 R alpha 1 (Luc) HEK293 Reporter Cell

For research use only.

描述(Description)

The Human IL-4 R alpha/IL-13 R alpha 1 (Luc) HEK293 Reporter Cell with endogenous IL-4 R alpha and IL-13 R alpha 1 expression was engineered to express STAT6 signaling response element. When stimulated with human IL-4 or IL-13 protein, receptor-mediated signaling can drive STAT6-mediated luminescence. Neutralization of biological effect of human IL-4 or IL-13 protein by corresponding antibody results in a decrease in luminescence.

应用说明(Application)

• Screen for neutralizing antibodies blocking the stimulation of human IL-4 or IL-13 protein.

Application

IL-4 R alpha/IL-13 R alpha 1 APPLICATION

Inhibition of human IL-4 protein-induced reporter activity by anti-human IL-4 R alpha neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IL-4 protein (Cat. No. IL4-H4218) with a final concentration of 0.002 μg/mL. The EC50 of anti-human IL-4 R alpha neutralizing antibody is approximately 0.0073 μg/mL.

Protocol

IL-4 R alpha/IL-13 R alpha 1 APPLICATION

Inhibition of human IL-13 protein-induced reporter activity by anti-human IL-4 R alpha neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IL-13 protein (Cat. No. IL3-H52H4) with a final concentration of 0.1 μg/mL. The EC50 of anti-human IL-4 R alpha neutralizing antibody is approximately 0.0027 μg/mL.

背景(Background)

Interleukin-4 is a key cytokine associated with allergy and asthma. In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, And this cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. Recently, researcher found that the cytokine IL-4 plays a key role in development of innate CD8+ T cells in the thymus of several gene-deficient mouse strains, including Itk, KLF2, CBP and Id3, without previous exposure to antigen.
