Specifications

Description
CHGA (Chromogranin A) encodes a protein involved in the production of secretory vesicles in endocrine and neuroendocrine cells. Levels of this protein correlate with the number of secretory vesicles present, and staining of this protein is useful for subtyping neuroendocrine tumors in multiple tissues including the lung. Serum of patients with small cell lung cancer can be checked for circulating CHGA, and in this context it has been shown to have more sensitivity than neuroendocrine marker NSE. Sensitivity of CHGA is expected to increase with stage. Staining for Chromogranin A is expected to be cytoplasmic.

Immunogen
Recombinant full-length human Chromogranin A (CHGA) protein. Antigen Molecular Weight: 68-75 kDa
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.
