Synaptobrevins/vesicle-associated membrane proteins (VAMPs) together with syntaxins and a synaptosome-associated protein of 25kDa (SNAP-25) are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane (1). The terminal step of cytokinesis in animal cells is the abscission of the midbody, a cytoplasmic bridge that connects the two prospective daughter cells. It has been shown that two members of the SNARE membrane fusion machinery, syntaxin 2 and endobrevin/VAMP8, specifically localize to the midbody during cytokinesis in mammalian cells (2). It has been established that VAMP8/endobrevin is a major player in regulated exocytosis of the exocrine pancreas. VAMP8 is enriched on the membrane of zymogen granules and exists in a complex with syntaxin 4 and SNAP-23. Results suggest a major physiological role of VAMP8 in regulated exocytosis of pancreatic acinar cells by serving as a v-SNARE of zymogen granules (3). Applications: Suitable for use in Flow Cytometry, ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:10,000-1:20,000 Immunohistochemistry: 1:100-1:250 Immunocytochemistry: 1:100-1:250 Flow Cytometry: 1:80 Immunoprecipitation: 1:20 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
