Product Overview
This rabbit polyclonal antibody targets CD70 antigen in mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 21.9 kDa, and the supplier reports an observed band at about 30 kDa.
CD70 is a TNF family ligand expressed transiently on activated lymphocytes and dendritic cells. It binds the receptor CD27 to support T-cell activation, expansion and memory formation, and it is studied in immune co-stimulation and in tumors that express it aberrantly.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat spleen tissue, rat thymus tissue, rat lung tissue, rat L6 cells, rat PC-12 cells, mouse B16 cells, mouse spleen tissue, mouse thymus tissue, mouse lung tissue, mouse RAW264.7 cells, mouse ANA-1 cells, mouse SP2/0 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): mouse lymphonode tissue, mouse spleen 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 mouse Cd70 fragment (Cys36–Gln191), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places CD70 antigen in the cell membrane. Tissue expression noted by UniProt (mouse): Very low level of expression. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
