Product Overview
This rabbit polyclonal antibody targets ras-related protein Rab-3A (gene RAB3A) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 25.0 kDa, and the supplier reports an observed band at about 25 kDa.
Rab3A (RAB3A) is a Rab GTPase on synaptic vesicles and secretory granules. In its GTP-bound form it recruits effectors such as RIM and rabphilin to help vesicles dock at release sites, and it regulates neurotransmitter release and synaptic plasticity.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat, Human) |
|---|
Samples with a confirmed band (WB): rat brain tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human rab3A. It differs from the mouse and rat sequences at two residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ras-related protein Rab-3A in the cytoplasm, lysosome, cytoplasmic vesicle and cell projection. Tissue expression noted by UniProt (human): Specifically expressed in brain. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
