Description
Chromogranin A is a 439 amino acid protein which is encoded on chromosome 14 and 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.
CHGA Human Recombinant is a single, glycosylated polypeptide chain containing 445 amino acids (19-457a. A) and having a molecular mass of 49.7kDa (calculated). CHGA is fused to a 6 a. A His tag at C-terminal
