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.

Application Notes

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.
1. This HER2 antibody binds to the extracellular/cell surface region of the protein.


Recombinant human HER2 protein was used as the immunogen for this antibody.(1)


Store the HER2 / ErbB2 antibody at 2-8°C.
