Detects human, mouse, and rat VAMP-2 in direct ELISAs and Western blots. In direct ELISAs, less than 10% cross-reactivity with recombinant human (rh) VAMP-1 is observed and less than 2% cross-reactivity with rhVAMP-3 and rhVAMP-7 is observed.

Detection of Human, Mouse, and Rat VAMP‑2 by Western Blot.
Western blot shows lysates of Nalm‑6 human Pre-B acute lymphocytic leukemia cell line, SH‑SY5Y human neuroblastoma cell line, mouse brain tissue, and rat testis tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat VAMP‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5136) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). 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 8.
Vesicle-Associate Membrane Protein 2 (VAMP-2) was detected in perfusion-fixed frozen sections of rat spinal cord using a Goat Anti-Human/Mouse/Rat VAMP-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5136). The cells were stained with the NorthernLights 557-conjugated Donkey Anti-Goat IgG Affinity-purified Secondary Antibody (red; Catalog # NL001). The cell nuclei were counterstained with DAPI (blue). VAMP-2 immunoreactivity was localized to synaptic vesicles. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

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.
