Immunofluorescent analysis of VAMP3 (green) showing staining in the cytoplasm of NIH-3T3 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a VAMP3 polyclonal antibody (Product # PA1-767A) in 3% BSA-PBS at a dilution of 1:50 and incubated overnight at 4°C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. Actin was stained using Alexa Fluor 554 (red) and nuclei were stained with Hoechst or DAPI (blue). Images were taken at a magnification of 60x.

PA1-767A detects vesicle-associated membrane protein 3 (VAMP-3)/cellubrevin in human, rat and mouse samples.
PA1-767A has been successfully used in Western blot and ICC/IF procedures. By Western blot, this antibody detects an ~13 kDa protein representing VAMP-3 in HeLa cell lysates.
PA1-767A immunogen is a sythetic peptide corresponding to residues M(1) S T G V P S G S S A A T G S N R R(18) C of mouse VAMP-3. This immunizing peptide (Cat. # PEP-145) is available for use in neutralization and control experiments.
The vesicle associated membrane proteins (VAMP) or synaptobrevins are calcium binding proteins specific to eukaryotes. VAMPs, along with synaptosomal associated protein of 25 kDa (SNAP-25) and syntaxin, form the core complex of soluble NSF attachment protein receptor (SNARE) proteins that interact with the soluble proteins N-ethylmaleimide-sensitive factor (NSF) and alpha-SNAP. These membrane associated proteins play a key role in the regulation of vesicle membrane fusion with the plasma membrane. The Clostridium tetani neurotoxin is a metalloprotease with specificity for VAMP. In Alzheimer"e;s disease, all VAMP isoform levels appear to be significantly reduced.

SNAP23, Syntaxin4, and vesicle-associated membrane protein 7 (VAMP7) mediate trafficking of membrane type 1-matrix metalloproteinase (MT1-MMP) during invadopodium formation and tumor cell invasion.
PA1-767A was used in western blot to study the trafficking of MT1-MMP to invadopodia during tumor invasion and the roles played by SNAP23, syntaxin-4 and VAMP7
