Synaptophysin1 antibody - 101 011C2 K.O.

Synaptophysin is a major synaptic vesicle membrane protein and a useful neuroendocrine tumor marker
Mouse monoclonal purified IgG
Cat. No.: 101 011C2
Amount: 50 µg
Price: $475.00
Cat. No. 101 011C2 50 µg purified IgG, lyophilized, fluorescence-labeled with Cyanine 2.

Fluorescence labeled antibodies conjugated to Cyanine dyes are well suited for standard epi-fluorescence setups and confocal microscopy.

Cyanine 2: λex 492 nm / λem 508 nm
Sulfo-Cyanine 3: λex 554 nm / λem 568 nm
Sulfo-Cyanine 5: λex 649 nm / λem 667 nm

Cyanine 5 dyes are well suited for STORM high resolution microscopy.
Sulfo-Cyanines are highly water soluble and allow a higher labeling degree and consequently brighter conjugates.

Albumin and azide were 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.

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

Synaptophysin1, 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.
Synaptophysin1 has four transmembrane domains with both N- and C-terminus facing the cytoplasm. It binds to synaptobrevin1 and synaptobrevin2 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, synaptophysin1 represents a small protein family with two additonal members, synaptoporin (synaptophysin2) and panthophysin. Like synaptophysin1, synaptoporin is widely expressed in neurons and colocalizes with synaptophysin1 on synaptic vesicles whereas panthophysin is expressed in all tissues.
