Product Overview
This rabbit polyclonal antibody targets ubiquitin-protein ligase E3A (gene UBE3A) in human samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 100.7 kDa, and the supplier reports an observed band at about 100 kDa.
UBE3A (also called E6AP) is a HECT-type E3 ubiquitin ligase that receives ubiquitin from an E2 enzyme and transfers it to its substrates, marking many of them for proteasomal degradation. It is well known for its role in brain development, since loss of maternal UBE3A causes Angelman syndrome, and for being recruited by the HPV E6 oncoprotein to degrade p53.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Mouse, Rat) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human 293T cells, human Jurkat cells, human K562 cells, human HepG2 cells, human HeLa 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 brain tissue, human gastric 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 a confirmed signal (flow cytometry): Caco-2 cells.
Immunogen
Recombinant human UBE3A fragment (Met1–Glu860), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ubiquitin-protein ligase E3A in the cytoplasm and nucleus. 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).
