Description
Fyn (Phospho-Tyr530) Cell-Based ELISA Kit
The Fyn (Phospho-Tyr530) Cell-Based ELISA Kit is a convenient, lysate- free, high throughput and sensitive assay kit that can monitor Fyn phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated Fyn in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Fyn phosphorylation.
How does our Fyn (Phospho-Tyr530) Fluorometric Cell-Based ELISA Kit work?
Qualitative determination of Fyn (Phospho-Tyr530) concentration is achieved by an indirect ELISA format. In essence, Fyn (Phospho-Tyr530) is captured by Fyn (Phospho-Tyr530)-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 Fyn (Phospho-Tyr530) is also provided for normalization purposes. The RFU values obtained for non-phosphorylated Fyn can be used to normalize the RFU value for phosphorylated Fyn. |

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. |

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. |

Fyn (Phospho-Tyr530) - Protein Information
| UniProt Protein Function: | Fyn: a tyrosine kinase of the Src family. Implicated in the control of cell growth. Plays a role in the regulation of intracellular calcium levels. Required in brain development and mature brain function with important roles in the regulation of axon growth, axon guidance, and neurite extension. Blocks axon outgrowth and attraction induced by NTN1 by phosphorylating its receptor DDC. Associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the fyn-binding protein. Three alternatively spliced isoforms have been described. Isoform 2 shows a greater ability to mobilize cytoplasmic calcium than isoform 1. Induced expression aids in cellular transformation and xenograft metastasis. In squamous cell carcinoma, Fyn transduces signals from EGFR and Src and is required for cell migration and invasiveness. Activity linked to migration in a murine melanoma model. Appears to block late stage development of neuroblastoma. Mouse knockout deficient in kindling response, a model for human epilepsy. |

| NCBI Summary: | This gene is a member of the protein-tyrosine kinase oncogene family. It encodes a membrane-associated tyrosine kinase that has been implicated in the control of cell growth. The protein associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the fyn-binding protein. Alternatively spliced transcript variants encoding distinct isoforms exist.
