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.
Suitable for use in Immunoblot, Immunofluorescence and Immunohistochemistry (frozen and paraffin-embedded tissue and cytological material; Do not use protease pretreatment).
Immunohistochemistry: 1:50 with PBS, pH 7.4; Incubation Time 1 hr at RT; extended with paraffin.
Storage and Stability:
Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile 40-50% glycerol and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
