Product Overview
This rabbit polyclonal antibody detects CD226 antigen in mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 38.1 kDa, and the supplier reports an observed band at about 70 kDa.
CD226, also called DNAM-1, is an activating receptor on NK cells, cytotoxic T cells and other lymphocytes. It binds CD155 (PVR) and CD112 (nectin-2), promoting adhesion, cytotoxicity and cytokine secretion, and it is studied alongside TIGIT in tumor immunity and immune checkpoint research.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse, Rat) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat spleen tissue, mouse spleen tissue, mouse thymus tissue, mouse RAW264.7 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 lung tissue, rat lung lymphaden 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): NRK cells.
Immunogen
Recombinant mouse CD226 fragment (Glu31–Leu333), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places CD226 antigen in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
