General description
The ErbB-2 proto-oncogene, also called Neu, EGFR-2 or HER-2, is a member of the transmembrane receptor tyrosine kinase family, which also includes EGF receptor and EGFR-3 (HER-3 or ErbB-3). Although, ErbB-2 does not have any known high-affinity ligands, its kinase activity can be activated without ligand by either overexpression or heteroassociation with other members of the ErbB family. Amplification of the ErbB-2 gene and overexpression of its product has been detected in almost 40% of primary human breast tumors, which correlates with poor prognosis in node positive breast cancer. ErbB-2 overexpression is also observed in ovarian, gastric, salivary and non-small cell lung carcinomas. Because of this, ErbB-2 is one of the major drug targets for breast cancer and other cancer treatments.
Specificity
Predicted to cross react with rat based on conservation of immunogenic sequence.
Recognizes and is specific for the activated form of erbB-2/HER-2 oncoprotein, MW ~138 kDa.
Immunogen
Epitope: Tyr1248
Synthetic phosphopeptide, residues 1243-1255, corresponding to a major auto-phosphorylation (Tyr1248) site of human erbB-2/HER-2 (C-AENPEpYLGLDVPV).
Application
Immunohistochemistry:
IHC was performed by an independent laboratory.
Immunocytochemistry:
2 µg/mL of a previous lot showed positive immunostaining for phospho-erbB2/HER-2 in EGF treated A431 cells.

It is well documented that human epidermal growth factor receptor 2 (HER2) overexpression/amplification is associated with poor survival in breast cancer patients. However, it is largely unknown whether HER2 somatic mutations are associated with survival in HER2-negative breast cancer patients.
