Specificity K.O. validated
Remarks

This antibody is a chimeric antibody based on the well known monoclonal mouse antibody clone 7.2. The constant regions of the heavy and light chains have been replaced by chicken specific sequences. Therefore, the antibody can be used with standard anti-chicken secondary reagents. The antibody has been expressed in mammalian cells.
Synaptophysin1 is widely used as marker for nerve terminals and neuroendocrine tumors. For still unknown reason, neuronal synaptophysin is better recognized than neuroendocrine synaptophysin. If this is a problem, the polyclonal rabbit antibody, cat. no. 101 002 or 101 203, is 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.
