Chromogranin A Antibody (SPM339) [Janelia Fluor® 646] Summary

• Immunogen: Human pheochromocytoma
• 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.

FAQs for Chromogranin A Antibody (NBP2-34764JF646). (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.
