General description

Synaptophysin is a 38 kDa glycoprotein present in the membrane of neuronal presynaptic vesicles in brain, spinal cord, retina, vesicles of adrenal medulla, neuromuscular junctions, and endocrine cells. It is also expressed by neuroendocrine cells throughout the body, both normal and neoplastic. Synaptophysin is a useful marker for the identification of normal neuroendocrine cells and neuroendocrine neoplasms. This antibody reacts with neuroendocrine cells of human adrenal medulla, carotid body, skin, pituitary gland, thyroid, lung, pancreas, and gastointestinal mucosa. It also reacts with a wide spectrum of neuroendocrine neoplasms of neural type including neuroblastomas, ganglioneuroblastomas, ganglioneuromas, pheochromocytomas, chromaffin, and non chromaffin paragangliomas.

Specificity

The antibody reacts with presynaptic vesicles of cerebral and spinal neurons, of neuromuscular endplates and with the retina of man, cow, rat and mouse. The antibody also reacts with vesicles of adrenal medulla and islet cells, and additionally allows specific staining of neuronal, adrenal and neuroepithelial tumors, such as pheochromocytoma, paraganglioma, islet cell tumors (incl. Insulinoma), medullary thyroid carcinoma and diverse pulmonary and gastro-intestinal carcinoids. The antibody also stains neurosecretory vesicles of certain culture cells, e.g. of the rat cell line PC-12.

Immunogen

Vesicular fraction of bovine brain. The SY38 epitope is to a pentapeptide repeat structure in the carboxy-terminal cytoplasmic tail of synaptophysin (Knaus & Betz 1990).

Application

Detect Synaptophysin using this Anti-Synaptophysin Antibody, clone SY38 validated for use in FC, IC, IH & WB.
Flow Cytometry (FACS):
A previous lot of this antibody was used in Flow Cytometry.

Western Blot:
(Provoda, 2000) Reacts with a 38 kDa transmembrane glycoprotein

Immunohistochemistry:
For relatively cytoplasm-rich neuroendocrinic tumors a final concentration of 1 µg/mL is recommended. Concerning cytoplasm deficient tumors a concentration of 2 µg/mL should be used. Ideal frozen sections (4-5 mm) are obtained from shock-frozen tissue samples. The frozen sections are air-dried and then fixed with acetone for 5-10 min at -20°C. Excess acetone is allowed to evaporate at room temperature. Material fixed in alcohol or formalin and embedded in paraffin can also be used.
It is advantageous to block unspecific binding sites by overlaying the sections with fetal calf serum for 20-30 min at room temperature. Excess of fetal calf serum is removed by decanting before application of the anti-body solution.
Cytocentrifuge preparations of single cells or cell smears are also fixed in acetone. These preparations should but should be followed directly by antibody treatment.

Optimal working dilutions must be determined by end user.

Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been identified in a neurodevelopmental disorder characterized by early-onset intractable seizures, severe developmental delay, intellectual disability, and Rett's syndrome-like features. Since the physiological functions of CDKL5 still need to be

Children, after multiple exposures to general anesthesia, appear to be at an increased risk of developing learning disabilities. Almost all general anesthetics-including sevoflurane, which is commonly used for children-are potentially neurotoxic to the developing brain. Anesthesia exposure during development might
