Product Overview
This rabbit polyclonal antibody targets rabphilin-3A (gene RPH3A) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 76.9 kDa, and the supplier reports an observed band at about 85 kDa.
Rabphilin-3A (RPH3A) is a Rab3 effector with two C2 domains that bind Ca2+ and phospholipids. Recruited to synaptic vesicles by GTP-bound RAB3A, it influences vesicle docking and calcium-triggered neurotransmitter release, and at postsynaptic sites it has been shown to help stabilize GluN2A-containing NMDA receptors.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse, Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HeLa cells, 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.
Samples with confirmed staining (IHC): mouse brain tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human RPH3A fragment (Arg78–Gln564), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places rabphilin-3A in the cell projection, postsynaptic cell membrane and membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
