Description
Caveolin-1 (Phospho-Tyr14) Cell-Based ELISA Kit
The Caveolin-1 (Phospho-Tyr14) Cell-Based ELISA Kit is a convenient, lysate- free, high throughput and sensitive assay kit that can monitor Caveolin-1 phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated Caveolin-1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Caveolin-1 phosphorylation.
How does our Caveolin-1 (Phospho-Tyr14) Fluorometric Cell-Based ELISA Kit work?
Qualitative determination of Caveolin-1 (Phospho-Tyr14) concentration is achieved by an indirect ELISA format. In essence, Caveolin-1 (Phospho-Tyr14) is captured by Caveolin-1 (Phospho-Tyr14)-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 Caveolin-1 (Phospho-Tyr14) is also provided for normalization purposes. The RFU values obtained for non-phosphorylated Caveolin-1 can be used to normalize the RFU value for phosphorylated Caveolin-1. |

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. |

Add 50 µl of Primary Antibody Mixture NP to the corresponding wells for total Caveolin-1 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. |

Caveolin-1 (Phospho-Tyr14) - Protein Information
| UniProt Protein Function: | Caveolin-1: May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Involved in the costimulatory signal essential for T-cell receptor (TCR)- mediated T-cell activation. Its binding to DPP4 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3- dependent manner. Recruits CTNNB1 to caveolar membranes and may regulate CTNNB1-mediated signaling through the Wnt pathway. Homooligomer. Interacts with GLIPR2, NOSTRIN, SNAP25 and syntaxin. Interacts with rotavirus A NSP4. Interacts (via the N- terminus) with DPP4; the interaction is direct. Interacts with CTNNB1, CDH1 and JUP. Interacts with BMX and BTK. Expressed in muscle and lung, less so in liver, brain and kidney. Belongs to the caveolin family. 2 isoforms of the human protein are produced by alternative initiation. |

| NCBI Summary: | The scaffolding protein encoded by this gene is the main component of the caveolae plasma membranes found in most cell types. The protein links integrin subunits to the tyrosine kinase FYN, an initiating step in coupling integrins to the Ras-ERK pathway and promoting cell cycle progression. The gene is a tumor suppressor gene candidate and a negative regulator of the Ras-p42/44 mitogen-activated kinase cascade. Caveolin 1 and caveolin 2 are located next to each other on chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex. Mutations in this gene have been associated with Berardinelli-Seip congenital lipodystrophy. Alternatively spliced transcripts encode alpha and beta isoforms of caveolin 1.[provided by RefSeq, Mar 2010] |
