This antibody recognizes a protein of 185kDa, which is identified as HER2 / ErbB2. Its epitope is localized in the extracellular domain. ErbB2 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. ErbB2 protein is over-expressed in a variety of carcinomas especially those of breast and ovary.

Application Notes

Variations in protocols, secondaries and substrates may require the antibody to be titered for optimal performance.

1. This ErbB2 antibody binds to the extracellular/cell surface region of the protein.


Recombinant human protein was used as the immunogen for this ErbB2 antibody.(1)


Store the ErbB2 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
