Background
Chromogranin A (a protein of 439 amino acids which is encoded on chromosome 14) 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, phenochromocytomas, paragangliomas, and other neuroendocrine tumors. Coexpression of chromogranin A and neuron specific enolase (NSE) is common in neuroendocrine neoplasms.

FAQs for Chromogranin A Antibody (NB120-15160). (Showing 1 - 1 of 1 FAQs).
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.

The signal was developed using HRP-conjugated anti-rabbit secondary and DAB reagent which followed counterstaining of the section with hematoxylin. The antibody generated a strong staining in Islets of Langerhans. Also, in the periphery of the cells, the pattern of staining was punctate representing the vesicles with Chromogranin A.
