Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000
Immunoprecipitation 1:50

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

VAMP3 recognizes endogenous levels of total VAMP3 protein. This antibody does not cross-react with VAMP1 or VAMP2 proteins.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human VAMP3 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Proteins in the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex are integral membrane proteins involved in vesicle transport and membrane fusion by pairing of vesicular SNAREs (v-SNAREs) with cognate target SNAREs (t-SNAREs) (reviewed in 1,2). Vesicle associated membrane protein 3 (VAMP3), also known as cellubrevin, has a broad tissue distribution and localizes to endosomal compartments (3). VAMP3 interacts with the t-SNAREs syntaxin1, syntaxin4, SNAP23, and SNAP25 (4,5). Research studies indicate that VAMP3 is involved in transferrin receptor recycling to the plasma membrane (6) and in T-cell receptor recycling to immunological synapses (7). Inhibition of VAMP3 with tetanus toxin impairs membrane trafficking during cell migration (8).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
