  Antibody with azide - store at 2 to 8C. Antibody without azide - store at -20 to -80C.
• Immunogen: Human pheochromocytoma (Uniprot: P10645)
• Localization: Finely granular cytoplasmic
• Marker: Neuroendocrine Marker
• Specificity: Chromogranin A is present in neuroendocrine cells throughout the body, including the neuroendocrine cells of the large and small intestine, adrenal medulla and pancreatic islets. It is an excellent marker for carcinoid tumors, pheochromocytomas, paragangliomas, and other neuroendocrine tumors. Co-expression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms. Reportedly, co-expression of certain keratins and chromogranin indicates neuroendocrine lineage. The presence of strong anti-chromogranin staining and absence of anti-keratin staining should raise the possibility of paraganglioma. The co-expression of chromogranin and NSE is typical of neuroendocrine neoplasms. Most pituitary adenomas and prolactinomas readily express chromogranin.
• Isotype: IgG1 Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: CHGA
• Purity: Protein A or G purified

Applications/Dilutions

• Dilutions:
  • CyTOF-ready
  • Flow Cytometry 0.5-1ug/million cells
  • Immunocytochemistry/ Immunofluorescence 1-2ug/ml
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin 0.5-1ug/ml
• Application Notes: Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
  Optimal dilution for a specific application should be determined.

Background

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.

FAQs for Chromogranin A Antibody (NBP2-34709). (Showing 1 - 1 of 1 FAQ).

1. I have following question about antibodies against Chromogranin A. Your products list the species but canine is not included. Does it mean that the products cannot be used on canine tissues?
   • When we do not list a species, it means we have not tested an antibody to work with those samples. If we test an antibody and find that it does not work, we will list the species with a minus sign. Unfortunately, we haven't tried these abs on canine tissues and they may work, but we cannot guarantee it. If you would like to purchase one to try, you will be eligible for the Innovators Reward Program.
