HER2 Antibody ErbB2

SKU: orb385666

Description

This antibody recognizes a protein of 185kDa, which is identified as HER2 / ErbB2. Its epitope is localized in the extracellular domain. HER2 is a member of the EGFR family. This antibody is specific and shows minimal cross-reaction with other members of the EGFR-family. Receptors of this family are located on the plasma membrane and consist of an extracellular ligand-binding domain that is connected to a large intracellular domain by a single transmembrane sequence. HER2 / ErbB2 protein is over-expressed in a variety of carcinomas especially those of breast and ovary.
