Anti-Synaptophysin Antibody, clone SP15 (Ascites Free)

Synaptophysin (UniProt P08247; also known as Major synaptic vesicle protein p38) is encoded by the SYP (also known as MRX96, MRXSYP) gene (Gene ID 6855) in human. Synaptophysin is a 38 kDa four-transmembrane glycoprotein on synaptic vesicle (SV) with both its N- and C-termini exposed cytoplasmically. Synaptophysin forms homomultimers in the SV membrane and is heavily phosphorylated on tyrosine residues in its C-terminal pentapeptide repeats. Synaptophysin is also known to interact with SV v-SNARE protein synaptobrevin II (sybII) when sybII is not engaged with other SNARE proteins, suggesting a role of synaptophysin in sybII retrieval during SV endocytosis. Consistently, synaptophysin-knockout neurons display reduced levels of sybII at their nerve terminals.

This Anti-Synaptophysin Antibody, clone SP15 (Ascites Free) is validated for use in Western Blotting, Immunohistochemistry, Immunocytochemistry, ELISA for the detection of Synaptophysin.

Western Blotting Analysis: 1.0 µg/mL from a representative lot detected Synaptophysin in 10 µg of human brain tissue lysate.
Western Blotting Analysis: A representative lot detected synaptophysin in rat hippocampal tissue extracts (Lin, D., et al. (2012). Behav. Brain Res. 228(2):319-327).
Western Blotting Analysis: Representative lots detected synaptophysin in mouse brain synaptosomes preparations (Shim, S.Y., et al. (2008). J. Neurosci. 28(14):3604-3614).
Western Blotting Analysis: A representative lot detected synaptophysin in the large dense-core vesicles-containing fractions obtained by sucrose gradient centrifugation of rat brain median eminence (ME) neuroterminals preparations (Yin, W., et al. (2007). Exp. Biol. Med. (Maywood). 232(5):662-673).
Immunohistochemistry Analysis: A representative lot detected a stronger synaptophysin immunoreactivity in the inner molecular layer of frozen dentate gyrus sections from a 3-week old monkey, while a stronger immunoreactivity was seen in the outer molecular layer of dentate gyrus sections from a 13-year old monkey (Lavenex, P., et al. (2007). Dev. Neurosci. 29(1-2):179–192).
Immunohistochemistry Analysis: A representative lot immunostained nerve terminals at palisade ending using cat extraocular muscle (EOM) whole mount sections (Konakci, K.Z., et al. (2005). Invest. Ophthalmol. Vis. Sci. 46(1):155-165).
Immunohistochemistry Analysis: A representative lot detected synaptophysin immunoreactivity in human brain tissue sections (Honer, W.G., et al. (1993). Brain Res. 609(1-2):9-20).
Immunocytochemistry Analysis: A representative lot detected punctate synatophysin immunoreactivity among cultured primary cerebrocortical neurons from rat embryos (Bragina, L., et al. (2006). J. Neurochem. 99(1):134-141.).
ELISA Analysis: Representative lots were employed as the capture antibody for the detection of synaptophysin in human temporal cortex, frontal cortex, and cerebellar cortex extracts by sandwich ELISA (Klucken, J., et al. (2006). Acta Neuropathol. 111(2):101-108; Fukumoto, H., et al. (2002). Arch. Neurol. 59(9):1381-1389).
