ErbB2/Her2 Antibody (CB11) Summary

• Immunogen: The antibody recognizes human CD340.
• Specificity: Recognizes human CD340 (also known as Her2/neu and c-erb B-2), an oncoprotein expressed in approximately 20% of adenocarcinomas from sites such as breast, ovary and GI tract. In breast cancer CD340 expression has been correlated with poor prognosis. Clone CB11 has been reported as being suitable for use in Western blotting (1).

Background

The EGF receptor family comprises several related receptor tyrosine kinases that are frequently overexpressed in a variety of carcinomas. Members of this receptor family include EGFR (HER1), Neu (ErbB-2, HER2), ErbB-3 (HER3) and ErbB-4 (HER4), which form either homodimers or heterodimers upon ligand binding. Neu, a glycoprotein, undergoes transactivation upon heterodimerization with other EGF receptor family members. Neu heterodimerization with ErbB-3 recruits heregulin, which induces phosphoinositide (PI) 3-kinase activation. Activation of Neu potentiates tumor cell motility and protease secretion and invasion, and also modulates cell cycle checkpoint function, DNA repair and apoptotic responses. Amplification and/or overexpression of Neu occurs in 20-30% of breast carcinomas. Measurement of increased Neu expression can be a predictor of disease prognosis. Neu may also prove to be a promising target for therapeutic agents.
