Immunohistochemistry-Paraffin: Chromogranin A Antibody - BSA Free [NB120-15160]

Immunohistochemistry-Paraffin: Chromogranin A Antibody - BSA Free [NB120-15160]

Immunohistochemistry-Paraffin: Chromogranin A Antibody [NB120-15160] - IHC analysis of a formalin fixed paraffin embedded tissue section of mouse pancreas using Chromogranin A antibody at a dilution of 1:500. 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. Cells of lobules and acini showed a weak cytoplasmic and nuclear staining which is potentially the secreted pool of Chromogranin A.

Background: Chromogranin A

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.
