The IL-13Ralpha1 (Phospho-Tyr405) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect IL-13Ralpha1 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated IL-13Ralpha1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on IL-13Ralpha1 phosphorylation.
Qualitative determination of IL-13Ralpha1 (Phospho-Tyr405) concentration is achieved by an indirect ELISA format. In essence, IL-13Ralpha1 (Phospho-Tyr405) is captured by IL-13Ralpha1 (Phospho-Tyr405)-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:
| 1. | A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values. |
| 2. | Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted. |

| UniProt Protein Function: | IL13R: Binds with low affinity to interleukin-13 (IL13). Together with IL4RA can form a functional receptor for IL13. Also serves as an alternate accessory protein to the common cytokine receptor gamma chain for interleukin-4 (IL4) signaling, but cannot replace the function of IL2RG in allowing enhanced interleukin-2 (IL2) binding activity. Belongs to the type I cytokine receptor family. Type 5 subfamily. |
| UniProt Protein Details: | Protein type:Membrane protein, integral; Receptor, cytokine Chromosomal Location of Human Ortholog: Xq24 Cellular Component: interleukin-13 receptor complex; plasma membrane Molecular Function:hematopoietin/interferon-class (D200-domain) cytokine receptor activity; protein binding Biological Process: cell surface receptor linked signal transduction; cytokine and chemokine mediated signaling pathway |
| NCBI Summary: | The protein encoded by this gene is a subunit of the interleukin 13 receptor. This subunit forms a receptor complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors. This subunit serves as a primary IL13-binding subunit of the IL13 receptor, and may also be a component of IL4 receptors. This protein has been shown to bind tyrosine kinase TYK2, and thus may mediate the signaling processes that lead to the activation of JAK1, STAT3 and STAT6 induced by IL13 and IL4.
