Product Overview
This rabbit polyclonal antibody recognizes rab3 GTPase-activating protein non-catalytic subunit (gene RAB3GAP2) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 156.0 kDa, and the supplier reports an observed band at about 156 kDa.
RAB3GAP2 is the non-catalytic subunit of the Rab3 GTPase-activating complex, which inactivates Rab3 proteins and also acts as an exchange factor for Rab18. Mutations in RAB3GAP2 cause Martsolf syndrome and Warburg micro syndrome.

Samples with a confirmed band (WB): human K562 cells, human HL-60 cells, human THP-1 cells, human Raji cells, human HeLa cells, human HepG2 cells, mouse thymus tissue, mouse kidney tissue, mouse HEPA1–6 cells.
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, 50 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): human mammary cancer tissue, human rectal cancer tissue, mouse intestine tissue, rat intestine tissue, human colon cancer 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 citrate buffer (pH 6).
Immunogen
Recombinant human RAB3GAP2 fragment (Met1–Gln115), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places rab3 GTPase-activating protein non-catalytic subunit in the cytoplasm and endoplasmic reticulum. Tissue expression noted by UniProt (human): Ubiquitous. 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).
