The PEA-15 (Phospho-Ser104) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect PEA-15 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated PEA-15 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on PEA-15 phosphorylation.
Qualitative determination of PEA-15 (Phospho-Ser104) concentration is achieved by an indirect ELISA format. In essence, PEA-15 (Phospho-Ser104) is captured by PEA-15 (Phospho-Ser104)-specific primary (1ø) antibodies while the HRP-conjugated secondary (2ø) antibodies bind the Fc region of the 1ø antibody. Through this binding, the HRP enzyme conjugated to the 2ø 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: | PEA-15: an ubiquitously expressed anti-apoptotic protein. Inhibits both Fas- and Tnfrsf1a/Tnfr1-mediated caspase-8 activity and apoptosis. Interacts with CASP8/FLICE and FADD. Regulates glucose transport by controlling both the content of GLUT1 glucose transporters on the plasma membrane and the insulin-dependent trafficking of GLUT4 from the cell interior to the surface. Most abundant in tissues such as heart, brain, muscle and adipose tissue which utilize glucose as an energy source. Lower expression in glucose-producing tissues. Higher levels of expression are found in tissues from individuals with type 2 diabetes than in controls. |
| UniProt Protein Details: | Protein type:Motility/polarity/chemotaxis; Apoptosis Chromosomal Location of Human Ortholog: 1q21.1 Cellular Component: cytosol; microtubule associated complex Molecular Function:protein binding Biological Process: activation of MAPK activity; activation of MAPKK activity; apoptosis; axon guidance; carbohydrate transport; DNA damage checkpoint; epidermal growth factor receptor signaling pathway; fibroblast growth factor receptor signaling pathway; innate immune response; insulin receptor signaling pathway; MAPKKK cascade; negative regulation of glucose import; nerve growth factor receptor signaling pathway; Ras protein signal transduction; response to morphine; small GTPase mediated signal transduction; transport; vascular endothelial growth factor receptor signaling pathway |
| NCBI Summary: | This gene encodes a death effector domain-containing protein that functions as a negative regulator of apoptosis. The encoded protein is an endogenous substrate for protein kinase C. This protein is also overexpressed in type 2 diabetes mellitus, where it may contribute to insulin resistance in glucose uptake. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014] |
