The eEF2K Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect eEF2K protein expression profile in cells. The kit can be used for measuring the relative amounts of eEF2K in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on eEF2K.
Qualitative determination of eEF2K concentration is achieved by an indirect ELISA format. In essence, eEF2K is captured by eEF2K-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: | EEF2K: an atypical protein kinase of the Alpha family. Dependent on Ca2 ions and calmodulin. May play a key role linking cellular energy status and the inhibition of protein synthesis, a major consumer of metabolic energy. Phosphorylates and inactivates eEF2, resulting in the inhibition of peptide-chain elongation eEF2K is phosphorylated and activated by AMPK in response to elevated AMP levels, which increase during cellular stress and starvation. Regulated in response to a range of stimuli including TNF-alpha. Overexpressed in breast cancer cell lines and tumors. Activated in rat glioblastoma, and growth was inhibited by the drug Rottlerin. Activity induced in ischemic heart muscle |

| NCBI Summary: | This gene encodes a highly conserved protein kinase in the calmodulin-mediated signaling pathway that links activation of cell surface receptors to cell division. This kinase is involved in the regulation of protein synthesis. It phosphorylates eukaryotic elongation factor 2 (EEF2) and thus inhibits the EEF2 function. The activity of this kinase is increased in many cancers and may be a valid target for anti-cancer treatment. [provided by RefSeq, Jul 2008] |

For suspension cells and loosely attached cells, coat the plates with 100 µL of 10 µg/ml Poly-L-Lysine (not included) to each well of a 96-well plate for 30 minutes at 37°C prior to adding cells. |
