50 µg purified recombinant IgY, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |
| Applications | |
| Clone | Ch7.2 |
| Subtype | IgY (λ light chain) |
| Immunogen | Full-length recombinant rat synaptophysin (UniProt Id: P07825) |
| Epitop |
Epitop: AA 219 to 307 from rat Synaptophysin1 (UniProt Id: P07825) |
| Reactivity |
Reacts with: human (P08247), rat (P07825), mouse (Q62277), other mammals. Weaker signal: zebrafish, other vertebrates. Other species not tested yet. |
| 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 The constant regions of the heavy and light chains have been replaced by chicken specific sequences.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. |

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.
