Product Overview
This rabbit polyclonal antibody detects TGF-beta-activated kinase 1 and MAP3K7-binding protein 2 (gene TAB2) in human samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 76.5 kDa, and the supplier reports an observed band at about 76 kDa.
TAB2 is an adaptor that uses its NZF zinc finger to recognize Lys63-linked polyubiquitin chains and bring TAK1 into signaling complexes with TRAF6 and RIPK1. This recruitment activates TAK1 and, in turn, the IKK complex, JNK and NF-κB, and TAB2 is also linked to heart development.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| 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 HeLa cells, human A549 cells, human HepG2 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 1:5000, ECL detection.
Samples with confirmed staining (IHC): 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): U87 cells.
Immunogen
Recombinant human TAB2 fragment (Gln169–Lys522), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places TGF-beta-activated kinase 1 and MAP3K7-binding protein 2 in the membrane, endosome membrane, lysosome membrane and cytoplasm. Tissue expression noted by UniProt (human): Widely 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).
