Protein Array: Chromogranin A Antibody (CHGA/1815R) - Azide and BSA Free [NBP2-54363] - Analysis of Protein Array containing more than 19,000 full-length human proteins using Chromogranin A Antibody (CHGA/1815R). Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (Monoclonal Antibody) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SDs) above the mean value of all signals generated on that array. If targets on HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SDs) between the Z-score. S-score therefore represents the relative target specificity of a Monoclonal Antibody to its intended target. A Monoclonal Antibody is considered to specific to its intended target, if the Monoclonal Antibody has an S-score of at least 2.5.

Background: Chromogranin A

Chromogranin A (CgA) is an 86 kDa protein that is the major member of the granin family of acidic secretory glycoproteins located in neuroendocrine cells. CgA is believed to play a role in targeting peptide hormones and neurotransmitters to granules of the regulated pathways and inhibit hormone and neurotransmitter release. Also, the widespread distribution of CgA has made the measurement of circulating immunoreactive CgA a valuable tool in the diagnosis of neuroendocrine neoplasia, and CgA immunohistochemistry can help to identify the neuroendocrine nature of tumors. The N-terminal domain of CgA inhibits tumor necrosis factor a (TNFa) induced gap formation in human umbilical venous endothelial cells. CgA levels which reflect neuroendocrine differentiation of prostatic carcinoma may have a diagnostic, therapeutic and prognostic role in the management of prostate cancer patients.
