Technical Data
Synaptophysin (SYP, SYPH, SypI, Major Synaptic Vesicle Protein P38, Syn p38) (FITC)
Synaptophysin labels normal neuroendocrine cells of human adrenal medulla, carotid body, skin, pituitary gland, thyroid, lung, pancreas, gastrointestinal mucosa, Paneth’s cells in the gastrointestinal tract and of gastric parietal cells. Neurons in the brain, spinal cord, and retina are also labeled. Anti-synaptophysin reacts with neuroendocrine neoplasms of neural as well as epithelial types e.g. neuroblastomas, ganglioneuroblastomas. ganglioneuromas, pheo-chromocytomas, chromaffin, and non-chromaffin paragangliomas. Of the epithelial types include pituitary adenomas, islet cell neoplasms, medullathyroid carcinomas, parathyroid adenomas, carcinoids of the bronchopulmonary and gastro-intestinal tracts and neuroendocrine carcinomas of the skin. In combination with anti-chromogranin A and anti-NSE, anti-synaptophysin is very useful in the identification of normal neuroendocrine cells and neuroendocrine neoplasms.
