The Breast Tumor Kinase (Phospho-Tyr447) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Breast Tumor Kinase protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated Breast Tumor Kinase in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Breast Tumor Kinase phosphorylation.
Qualitative determination of Breast Tumor Kinase (Phospho-Tyr447) concentration is achieved by an indirect ELISA format. In essence, Breast Tumor Kinase (Phospho-Tyr447) is captured by Breast Tumor Kinase (Phospho-Tyr447)-specific primary (1ø) antibodies while the HRP-conjugated secondary (2ø) antibodies bind the Fc region of the 1ø antibody. Through this binding, the HRP enzyme conjugated to the 2ø 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: | Brk: a tyrosine kinase of the Src family. May function as an intracellular signal transducer in epithelial tissues. Very high level expression in colon and high levels in small intestine and prostate, and low levels in some fetal tissues. Selectively expressed in breast tumors and cell lines, and perhaps in colon and prostate cancers. Also found in melanocytes. Not expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Overexpression in mammary cells leads to EGF sensitization and results in a partially transformed phenotype. Enhances anchorage-independent growth and responsiveness to EGF. RNAi reduces proliferation in breast cancer cells. Kinase-inactive mutant indicates tumor function may be independent of catalytic function. |

| NCBI Summary: | The protein encoded by this gene is a cytoplasmic nonreceptor protein kinase which may function as an intracellular signal transducer in epithelial tissues. Overexpression of this gene in mammary epithelial cells leads to sensitization of the cells to epidermal growth factor and results in a partially transformed phenotype. Expression of this gene has been detected at low levels in some breast tumors but not in normal breast tissue. The encoded protein has been shown to undergo autophosphorylation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012] |

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. |
