Description
B-RAF (Phospho-Ser602) Cell-Based ELISA Kit
The B-RAF (Phospho-Ser602) Cell-Based ELISA Kit is a convenient, lysate- free, high throughput and sensitive assay kit that can monitor B-RAF phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated B-RAF in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on B-RAF phosphorylation.
How does our B-RAF (Phospho-Ser602) Fluorometric Cell-Based ELISA Kit work?
Qualitative determination of B-RAF (Phospho-Ser602) concentration is achieved by an indirect ELISA format. In essence, B-RAF (Phospho-Ser602) is captured by B-RAF (Phospho-Ser602)-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 B-RAF (Phospho-Ser602) is also provided for normalization purposes. The RFU values obtained for non-phosphorylated B-RAF can be used to normalize the RFU value for phosphorylated B-RAF. |

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. |

B-RAF (Phospho-Ser602) - Protein Information
UniProt Protein Function: | BRAF: a tyrosine kinase-like kinase of the RAF family. Involved in the transduction of mitogenic signals from the cell membrane to the nucleus. May play a role in the postsynaptic responses of hippocampal neuron. Frequently mutated in thyroid cancers, skin melanomas and at lower frequency in a wide range of human cancers. An activating mutation, mimicking phosphorylation of the activation loop, is seen in 60% of malignant melanoma samples. Raf mutations are generally exclusive to Ras activating mutations. Activating mutations are also seen in ~10% of colorectal cancers, in lung cancers and gliomas, and at a lower rate in several other tumors. Inactivating mutations are also seen and may result in activation of c-Raf and Erk. Mutations in B-Raf, MEK1 and MEK2 also associated with cardiofaciocutaneous syndrome, displaying morphological, cardiac and mental defects. Approved Inhibitor: Nexavar/Sorafenib. |

NCBI Summary: | This gene encodes a protein belonging to the raf/mil family of serine/threonine protein kinases. This protein plays a role in regulating the MAP kinase/ERKs signaling pathway, which affects cell division, differentiation, and secretion. Mutations in this gene are associated with cardiofaciocutaneous syndrome, a disease characterized by heart defects, mental retardation and a distinctive facial appearance. Mutations in this gene have also been associated with various cancers, including non-Hodgkin lymphoma, colorectal cancer, malignant melanoma, thyroid carcinoma, non-small cell lung carcinoma, and adenocarcinoma of lung. A pseudogene, which is located on chromosome X, has been identified for this gene. [provided by RefSeq, Jul 2008] |
