Product Overview
This rabbit polyclonal antibody recognizes nectin-3 (gene NECTIN3) in human samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 61.0 kDa, and the supplier reports an observed band at about 80 kDa.
Nectin-3 (NECTIN3, CD113) is an immunoglobulin superfamily adhesion molecule that binds other nectins and PVR (CD155) in trans. It helps form adherens junctions and specialized contacts such as Sertoli cell-spermatid junctions, and its interactions activate CDC42 and RAC signaling.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |

Samples with a confirmed band (WB): human U2OS whole cellhuman 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 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): A431 cells.
Immunogen
Recombinant human Nectin 3/NECTIN3 fragment (Glu92–Asn296), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places nectin-3 in the cell membrane, postsynaptic cell membrane and cell junction. Tissue expression noted by UniProt (human): Predominantly expressed in testis and placenta as well as in many cell lines, including epithelial cell lines. 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).
