This antibody recognizes Chromogranin A (68kD) and other related chromogranin polypeptides from human, monkey, and pig. Through immunohistochemistry, chromogranin has been demonstrated in several elements of the diffuse neuroendocrine system, including anterior pituitary, thyroid parafollicular C cells, parathyroid chief cells, pancreatic islet cells, intestinal enteroendocrine cells, and tumors derived from these cells. Chromogranin immunoreactivity was also seen in thymus, spleen, lymph nodes, fetal liver, neurons, the inner segment of rods and cones, the submandibular gland, and the central nervous system. Since it is widely distributed, the measurement of Chromogranin A has become a valuable tool in the investigation of neuroendocrine neoplasia.
