Product Overview
This rabbit polyclonal antibody detects nitric oxide synthase, inducible (gene NOS2) in human samples and is validated for IHC and Western blot. The predicted molecular weight is 131.1 kDa, and the supplier reports an observed band at about 131 kDa.
Inducible nitric oxide synthase (iNOS, NOS2) is expressed in macrophages and other cells after exposure to cytokines or microbial products such as LPS. Unlike the other isoforms, it produces large, sustained amounts of nitric oxide that contribute to killing of bacteria and tumor cells. iNOS is a standard marker of classically activated macrophages and inflammation.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): human HeLa cells, human Caco-2 cells, human SH-SY5Y 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): human brain 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
Synthetic peptide from the C-terminal region of human iNOS. It differs from the mouse sequence at five residues and from the rat sequence at four residues.
Reactivity Notes
The supplier lists reactivity with human. UniProt places nitric oxide synthase, inducible in the cytoplasm. Tissue expression noted by UniProt (human): Expressed in the liver, retina, bone cells and airway epithelial cells of the lung. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
