Product Overview
This rabbit polyclonal antibody targets nectin-2 (gene NECTIN2) in human and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 57.7 kDa, and the supplier reports an observed band at about 70–80 kDa.
Nectin-2 (NECTIN2, CD112) is an immunoglobulin superfamily adhesion protein that also regulates T-cell and NK cell activity. Binding to CD226 (DNAM-1) delivers an activating signal, whereas binding to PVRIG or TIGIT is inhibitory, which has made it a target of interest in immuno-oncology research.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Rat) |
| Immunocytochemistry / Immunofluorescence | 2 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 K562 cells, human HEK293 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): human mammary cancer tissue, rat testis 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 confirmed staining (ICC/IF): HeLa cells.
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Recombinant human Nectin 2/NECTIN2 fragment (Gln32–Glu348), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places nectin-2 in the cell membrane. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
