Technical Data
Synaptophysin (SYP, SYPH, SypI, Major Synaptic Vesicle Protein P38, Syn p38) (BIotin)
Synaptophysin labels normal neuroendocrine cells of human adrenal medulla, carotid body, skin, pituitary gland, thyroid, lung, pancreas, gastrointestinal mucosa, Paneths 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 FACS and Immunohistochemistry (frozen and paraffin embedded tissue and cytological material, Pretreatment: In no case protease pretreatment).

Recommended Dilution:
Immunohistochemistry: 1:10 with PBS, pH 7.4; Incubation Time 1 hr at RT.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20C or colder. Aliquots are stable for at least 6 months at -20C. 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.
