| c-erbB-2 is a membrane-associated oncoprotein having considerable sequence homology to EGFR. C-erbB-2 is the second member of the EGF receptor tyrosine kinase family of growth factor receptors. Overexpression of c-erbB-2/HER-2 is reportedly a marker of poor prognosis in node-positive and in defined subsets of node-negative breast cancer. Elevated levels of c-erbB-2/HER-2 has also been implicated in response to chemotherapy. |

| Catalog # | C0015X1 |
| Applications | Suitable for ELISA, Immunoprecipitation, Western Blot and Immunohistochemistry. Other applications have not been tested. |
| Recommended Dilution | Immunoprecipitation: 10ug/mg protein lysate (Use Protein A). |
| Western Blot: 5-10ug/ml for 2 hours at RT. |
| Immunohistochemistry (Formalin/paraffin): 2.5-5ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes. |
| Optimal dilutions to be determined by the researcher. |
| Positive Control | SKBR-3 cells, T47D cells or breast carcinomas. |
| Control Peptide | C0015-30: c-erbB2, aa1243-1255, Control Peptide (HER2, neu Receptor) |
