Description
This is a peptide mapping to the carboxy terminus of human Neu (HER2 or ErbB-2). The Neu/HER-2 (also known as EGFR-2 or ErbB-2) is a transmembrane tyrosine kinase receptor and a well-defined tumor antigen. Neu/HER-2 is a shared antigen among multiple tumor types. Patients with HER-2/neu protein-overexpressing breast, ovarian, non-small cell lung, colon, and prostate cancers have been shown to have a pre-existent immune response to Neu/HER-2 (1,2). Neu/HER-2 amplification/overexpression confers more aggressive and malignant characteristics on breast cancer cells. Patients with Neu/HER-2-amplified breast cancer have a worse prognosis than those with normal Neu/HER-2 expression (3).
Applications Reported
