Monoclonal Anti-HER2 antibody produced in mouse (C15-1318-479)

General description

Human epidermal growth factor receptor 2 (HER2), also known as Erb-b2 receptor tyrosine kinase 2 (ErbB2), is encoded by the gene mapped to human chromosome 17. The encoded protein is a member of epidermal growth factor family. HER2 membrane protein is characterized with a cysteine-rich extracellular ligand-binding domain, a hydrophobic membrane spanning region and an intracellular tyrosine kinase domain.This protein does not have a ligand., It either forms heterodimers with other family members or homodimer with itself, when expressed at very high levels, to get activated. HER2 is expressed at low level in normal tissues, but at high level in breast cancer tissues.

Immunogen

V-erb-b2 erythroblastic leukemia viral oncogene homolog 2, neuro/glioblastoma derived oncogene homolog (avian) recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collecation of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

Human epidermal growth factor receptor 2 (HER2) signaling pathway promotes cell proliferation and survival in majority of breast cancers. Thus, overexpression of this protein leads to breast cancer. Heterodimeric complex of HER2 and phosphatidylinositide 3-kinase (PI3K) is the most potent stimulator of the phosphatidylinositol-3-kinase (PI3K)/Akt anti-apoptosis pathway. Upregulated expression of HER2 is associated with the development of ovarian, colorectal, pancreatic, endometrial and gastric cancers. Trastuzumab, an antibody, works by binding to a domain in the external domain of HER2. This domain is missing in p95, a truncated form of HER2, and hence these cancer cells show resistance to trastuzumab. HER2 protein can be used as a prognostic marker and as a therapeutic option for gynecologic cancers.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Linkage
