Detection of Human and Mouse VAMP‑2 by Western Blot. Western blot shows lysates of Daudi human Burkitt's lymphoma cell line, Jurkat human acute T cell leukemia cell line, and mouse brain tissue. PVDF Membrane was probed with 0.1 µg/mL of Mouse Anti-Human/Mouse VAMP‑2 Monoclonal Antibody (Catalog # MAB5136) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for VAMP‑2 at approximately 13 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

VAMP-2 (vesicle associated membrane protein 2; also Synaptobrevin-2) is a 13 kDa member of the Synaptobrevin family of proteins. It is a type IV transmembrane (TM) protein (i.e.- a type II TM protein whose C-terminus is almost completely transmembrane) that is found in the presynaptic terminals of neurons. VAMP-2 is targeted to presynaptic vesicles following binding to Synaptophysin I. Dissociation allows for synaptic vesicle fusion at the synaptic cleft with subsequent granule release. Human VAMP-2 is 116 amino acids (aa) in length. It contains one acetylation site at Ser2, a vSNARE coiled-coil homology region (aa 31‑91), and a membrane-anchor domain (aa 95‑114). Over aa 1‑94, human VAMP-2 shares 100% and 99% aa identity with canine and mouse VAMP-2, respectively.
