|Specificity||HER2/neu (also known as c-erbB-2) is a member of the epidermal growth factor receptor (EGFR) family and is notable for its role in the pathogenesis of breast cancer and as a target of treatment. It is a cell membrane surface-bound tyrosine kinase and is normally involved in the signal transduction pathways leading to cell growth and differentiation. HER2 is a proto-oncogene located at the long arm of human chromosome 17(17q11.2-q12). Approximately 25-30 percent of breast cancers have an amplification of the HER2/neu gene or overexpression of its protein product. Overexpression of this receptor in breast cancer is associated with increased disease recurrence and worse prognosis. Because of its prognostic role as well as its ability to predict response to trastuzumab, breast tumors are routinely checked for overexpression of HER2/neu. Overexpression also occurs in other cancer such as osteosarcoma, ovarian cancer and stomach cancer.|
|Application Notes||Titer/Working Dilution: This antibody may be diluted to a titer of 1:50 to 1:100 in an ABC method. However, depending on the staining conditions employed, we suggest that final dilution should be determined by the user. Staining Protocol: We suggest an incubation period of 30-60 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation should be determined by the user. Formalin fixed paraffin embedded tissue sections require high temperature antigen unmasking with 10 mM citrate buffer, pH 6.0 prior to immunostaining. Positive Control: Angiosarcoma. Cellular localization: Membrane|
|Buffer||This antibody is supplied as cell culture supernatant and diluted in buffer pH 7.5, containing BSA and sodium azide as a preservative.|
|Storage||Store the antibody at 2-8o c. Do not use it beyond the expiration date stated on the label.|
|Restrictions||For Research Use. CE-certified for In Vitro Diagnostics (IVD) Use in the European Union|
