Description_x000D_ General description_x000D_ Anti-Synaptophysin antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the hybridoma SVP-38 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synaptosome preparation from rat retina. Synaptophysin is a glycoprotein containing four transmembrane domains with both N and C termini on the cytoplasm face._x000D_ Synaptophysin (SYP) is encoded by the gene mapped to human chromosome Xp11.23-p11.22. The encoded protein has a molecular mass of 38kDa and is exclusively localized to the membrane of presynaptic vesicles._x000D_ Specificity_x000D_ Anti-Synaptophysin antibody, Mouse monoclonal recognizes rat, human, guinea-pig, and pig synaptophysin_x000D_ Immunogen_x000D_ synaptosome preparation from rat retina. The isotype is determined by ELISA using Mouse Monoclonal Antibody Isotyping Reagents (Sigma ISO-2). The antibody is purified from culture supernatant of hybridoma cells grown in a bioreactor._x000D_ Application_x000D_ Anti-Synaptophysin antibody, Mouse monoclonal has been used in following immunochemical techniques:_x000D_ • Immunoblotting_x000D_ • Immunohistochemistry_x000D_ • Immunofluorescence_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Synaptophysin (SYP) facilitates neurotransmitter release and synaptic plasticity. It is also implicated in synaptic vesicle formation and exocytosis. Mutation in the gene increases the risk of susceptibility to schizophrenia. It is widely used as a potential marker to study the circulation of synapses in the brain and to discover the basic features of the life cycle of synaptic vesicles (SVs)._x000D_ Synaptophysin has also been implicated in the recycling of synaptic vesicles by associating with dynamin I, a GTPase required for endocytosis.
