Product Overview
This rabbit polyclonal antibody targets CD82 antigen in human samples and is validated for IHC and Western blot. The predicted molecular weight is 29.6 kDa, and the supplier reports an observed band at about 30–36 kDa.
CD82 (KAI1) is a tetraspanin that organizes membrane microdomains with integrins, growth factor receptors and other partners. It influences cell adhesion, migration and signaling, and it was first identified as a suppressor of metastasis in prostate cancer, which keeps it of interest in cancer research.

Validated Applications
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human) |
Samples with a confirmed band (WB): human Jurkat cells, human Raji cells, human U-87MG 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 tonsil 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 CD82 fragment (Ala98–Tyr267), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 69% and 67%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places CD82 antigen in the cell membrane and cytoplasmic vesicle. Tissue expression noted by UniProt (human): Lymphoid specific. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
