Data from SDS-PAGE analysis of Anti-HER2 antibody (Clone ERBB2/2453). Reducing lane (R) shows heavy and light chain fragments. NR lane shows intact antibody with expected MW of approximately 150 kDa. The data are consistent with a high purity, intact mAb.Analysis of Protein Array containing more than 19,000 full-length human proteins using HER-2 Mouse Monoclonal Antibody (ERBB2/2453). Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD’s) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD’s) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.  A MAb is considered to specific to its intended target, if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.

General Description of HER-2 / c-erbB-2 / neu / CD340.
Recognizes a protein of 185kDa, which is identified as c-erbB-2/HER-2/neu. Its epitope is localized in the extracellular domain. C-erbB-2/HER-2 is a member of the EGFR family. This MAb 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. c-erbB-2/HER-2 protein is over-expressed in a variety of carcinomas especially those of breast and ovary.

HER-2 / c-erbB-2 / neu / CD340 Previously Observed Antibody Staining Patterns

Observed Subcellular, Organelle Specific Staining Data:

Anti-ERBB2 antibody staining is expected to be primarily localized to the cytosol and plasma membrane.

Observed Antibody Staining Data By Tissue Type:

Variations in HER2 / ErbB2 / neu / CD340 antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. Low, but measureable presence of HER2 / ErbB2 / neu / CD340 could be seen inglandular cells in the fallopian tube, parathyroid gland, prostate, rectum, salivary gland, seminal vesicle, small intestine and thyroid gland, hematopoietic cells in the bone marrow, hepatocytes in liver, melanocytes in skin, pneumocytes in lung, squamous epithelial cells in the cervix, uterine, esophagus, tonsil and vagina and glandular cells in the fallopian tube, parathyroid gland, prostate, rectum, salivary gland, seminal vesicle and small intestine and thyroid gland. We were unable to detect HER2 / ErbB2 / neu / CD340 in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.

Observed Antibody Staining Data By Tissue Disease Status:

Tissues from cancer patients, for instance, have their own distinct pattern of HER2 / ErbB2 / neu / CD340 expression as measured by anti-HER2 / ErbB2 / neu / CD340 antibody immunohistochemical staining. The average level of expression by tumor is summarized in the table below. The variability row represents patient to patient variability in IHC staining.
