Product Overview
This rabbit polyclonal antibody detects ADP-ribosylation factor-binding protein GGA3 in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 78.3 kDa, and the supplier reports an observed band at about 90 kDa.
GGA3 is a Golgi-localized, γ-ear-containing, ARF-binding clathrin adaptor that sorts cargo with acidic-cluster dileucine motifs between the trans-Golgi network and endosomes. It also targets ubiquitinated cargo, and it helps send the amyloid-processing enzyme BACE1 to lysosomes for degradation, linking GGA3 to Alzheimer's disease research.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human SH-SY5Y cells, human HEL cells, human K562 cells, human HL-60 cells, human T-47D 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, 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): human liver cancer tissue, human pancreatic cancer tissue, human rectal 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 EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): Caco-2 cells.
Samples with a confirmed signal (flow cytometry): Raji cells.
Immunogen
Recombinant human GGA3 fragment (Glu7–Pro535), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ADP-ribosylation factor-binding protein GGA3 in the endosome membrane, early endosome membrane and recycling endosome membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed. 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).
