Product Overview
This rabbit polyclonal antibody targets NAD(P)H dehydrogenase (gene NQO1) in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 30.9 kDa, and the supplier reports an observed band at about 31 kDa.
NAD(P)H quinone oxidoreductase 1 (NQO1) is a flavoprotein that reduces quinones directly to hydroquinones in a two-electron step, avoiding reactive semiquinone intermediates. It is a classic NRF2 target gene and also stabilizes proteins such as p53. NQO1 is studied in antioxidant defense, xenobiotic metabolism and cancer, and it is often overexpressed in tumors.

Validated Applications
| Western blot | 0.1–0.25 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human MCF-7 cells, human HeLa cells, human A549 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 0.25 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon cancer tissue, human ovarian 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 confirmed staining (ICC/IF): HeLa cells.
Samples with a confirmed signal (flow cytometry): MCF-7 cells.
Immunogen
Recombinant human NQO1 fragment (Met1–Lys274), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places NAD(P)H dehydrogenase in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
