- Description
| Specificity Profile | More Information |
 | The specificity of HER2/ERBB2 Monoclonal Antibody (CSB0032) was tested on the Membrane Proteome Array™ and shown to be specific for human HER2/ERBB2. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |

| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/ml |
 | JS-1 cells transiently transfected with human HER2/ERBB2 were stained with HER2/ERBB2 Monoclonal Antibody (CSB0032) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. JS-1 cells transiently transfected with an empty control vector were also stained with HER2/ERBB2 Monoclonal Antibody (CSB0032) (blue). | |

HER2 (also known as ERBB2) is a single-pass transmembrane protein and member of the epidermal growth factor (EGF) receptor family. This tyrosine kinase does not have a ligand-binding domain. Instead, HER2 stabilizes ligand binding and enhances activation of signaling pathways by forming a heterodimer with ligand-binding EGF receptor family members. HER2 regulates outgrowth and stabilization of peripheral microtubules and is overexpressed in multiple types of cancer, including breast and ovarian cancers. (NCBI Gene: 2064, UniProtKB/Swiss-Prot: P04626). Other names: ERBB2, NEU, CD340, NGL, MLN19, VSCN2, TKR1
