Description
ETK (Phospho-Tyr566) Cell-Based ELISA Kit
The ETK (Phospho-Tyr566) Cell-Based ELISA Kit is a convenient, lysate- free, high throughput and sensitive assay kit that can monitor ETK phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated ETK in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on ETK phosphorylation.
How does our ETK (Phospho-Tyr566) Fluorometric Cell-Based ELISA Kit work?
Qualitative determination of ETK (Phospho-Tyr566) concentration is achieved by an indirect ELISA format. In essence, ETK (Phospho-Tyr566) is captured by ETK (Phospho-Tyr566)-specific primary (1°) antibodies while Dye 1-conjugated and Dye 2-conjugated secondary (2°) antibodies bind the Fc region of the 1° antibody. Through this binding, the dye conjugated to the 2° antibody can emit light at a certain wavelength given proper excitation, hence allowing for a fluorometric detection method. 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 RFU values. |
| 2. | An antibody against the nonphosphorylated counterpart of ETK (Phospho-Tyr566) is also provided for normalization purposes. The RFU values obtained for non-phosphorylated ETK can be used to normalize the RFU value for phosphorylated ETK. |

Kit Protocol
This is a summarized version of the kit protocol. Please view the technical manual of this kit for information on sample preparation, reagent preparation and plate lay out.
| 1. | Seed 200 µl of desired cell concentration in culture medium into each well of the 96-well plates. 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. |
| 2. | Incubate the cells for overnight at 37°C, 5% CO2. |
| 3. | Treat the cells as desired. |
| 4. | Remove the cell culture medium and rinse with 200 µl of 1x TBS, twice. |
| 5. | Fix the cells by incubating with 100 µl of Fixing Solution for 20 minutes at room temperature. The 4% formaldehyde is used for adherent cells and 8% formaldehyde is used for suspension cells and loosely attached cells. |
| 6. | Remove the Fixing Solution and wash the plate 3 times with 200 µl 1x Wash Buffer for 3 minutes. The plate can be stored at 4°C for a week. |
| 7. | Add 100 µl of Quenching Buffer and incubate for 20 minutes at room temperature. |
| 8. | Wash the plate 3 times with 1x Wash Buffer for 3 minutes each time. |
| 9. | Dispense 200 µl of Blocking Buffer and incubate for 1 hour at room temperature. |

| 11. | Add 50 µl of Primary Antibody Mixture P to corresponding wells for ETK (Phospho-Tyr566) detection. Add 50 µl of Primary Antibody Mixture NP to the corresponding wells for total ETK detection. Cover the plate with parafilm and incubate for 16 hours (overnight) at 4°C. If the target expression is known to be high, incubate for 2 hours at room temperature. |

| NCBI Summary: | This gene encodes a non-receptor tyrosine kinase belonging to the Tec kinase family. The protein contains a PH-like domain, which mediates membrane targeting by binding to phosphatidylinositol 3,4,5-triphosphate (PIP3), and a SH2 domain that binds to tyrosine-phosphorylated proteins and functions in signal transduction. The protein is implicated in several signal transduction pathways including the Stat pathway, and regulates differentiation and tumorigenicity of several types of cancer cells. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2016] |
