Synaptophysin 1 - 101 011C5

Major synaptic vesicle membrane protein; neuroendocrine tumor marker
Monoclonal mouse purified IgG
Cat. No.: 101 011C5
Amount: 50 µg
Price: $465.00
Cat. No. 101 011C5 50 µg purified IgG, lyophilized, fluorescence-labeled with Oyster® 650

Fluorescence labeled antibodies conjugated to Oyster dyes from Luminartis GmbH (formerly Denovo Biolabels) allow the usage of established CyDye fluorescence detection systems. Oyster-488 has similar exitation and emission properties as Cy2, Oyster-550 as Cy3, and Oyster-650 is comparable to Cy5.
For our custom antibody labeling service Oyster-500 is also available.
Oyster dyes do not form dimers and therefore exhibit less internal quenching. This allows a higher labeling degree and consequently brighter conjugates.

Oyster dyes, Oyster-488, Oyster-500, Oyster-550, and Oyster-650 are trademarks of Luminartis GmbH, Muenster/Germany.

. Albumin was added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.The mounting agent Aquatex®(Merck Chemicals) is not compatible with Oyster dyes!

Reactivity Reacts with: human (P08247), rat (P07825), mouse (Q62277), mammals.
Weaker signal: zebrafish, other vertebrates.
Other species not tested yet.
Specificity Specific for synaptophysin 1, no cross-reactivity to other synaptophysins. K.O.
Remarks

Widely used as marker for nerve terminals and neuroendocrine tumors. For unknown reason, neuronal synaptophysin is better recognised than neuroendocrine synaptophysin. If this is a problem, the polyclonal rabbit antibody, cat. no. 101 002 or 101 203 are recommended.

Background

Synaptophysin 1, also referred to as p38-1, is a membrane glycoprotein of synaptic vesicles that is ubiquitously expressed in all neurons and in many endocrine cells. It is currently the most widely used marker for nerve terminals and probably the best marker for the pathologist in differentiating neuroendocrine tumors.
Synaptophysin 1 has four transmembrane domains with both N- and C-terminus facing the cytoplasm. It binds to synaptobrevin 1 and synaptobrevin 2 in detergent extracts but its function has not been elucidated completely. It forms a complex with dynamin at high Ca2+ concentration suggesting an involvement in synaptic vesicle endocytosis. As typical for synaptic vesicle proteins, synaptophysin 1 represents a small protein family with two additonal members, synaptoporin (synaptophysin 2) and panthophysin. Like synaptophysin 1, synaptoporin is widely expressed in neurons and colocalizes with synaptophysin 1 on synaptic vesicles whereas panthophysin is expressed in all tissues.
