SpecificityDetects a ~18kD protein in WB, corresponding to predicted size of VAMP from human, mouse, rat, bovine, guinea pig, hamster, monkey, porcine, rabbit, sheep and Xenopus tissue. This antibody detects VAMP1 (amino acids 1-118) and VAMP2 (amino acids 33-96)-GST fusion proteins expressed in E. coli. No reactivity was seen with a ~18kD protein in mouse liver extracts.
Tissue/ cell preparation (Human).
Mice were immunized with synaptic vesicle containing fractions which were immunoprecipitated from human brain homogenates using anti-human synaptophysin monoclonal antibodies.
Storage instructionsShipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000. Predicted molecular weight: 13 kDa.
RelevanceSynaptobrevins are highly conserved between vertebrates and invertebrates. It is a major constituent of synaptic vesicles and peptidergic secretory granules in all neurons examined so far. In addition, it is present on secretory granules of neuroendocrine cells.
Synaptobrevins, Syntaxins, and the 25 kDa synaptosomal associated protein SNAP25 are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane.
Cellular localizationCytoplasmic vesicle › secretory vesicle › synaptic vesicle membrane. Single-pass type IV membrane protein. Cell junction > synapse > synaptosome. Isoform 3 is found in mitochondria, mitochondrial outer membrane.
