Product nameAnti-iNOS antibody
See all iNOS primary antibodies
DescriptionRabbit polyclonal to iNOS
SpecificityThis antibody detects iNOS. It does not detect other NOS isoforms. By western blot, this antibody detects an ~135 kDa protein representing recombinant human iNOS. By western blot, this antibody also detects purified recombinant mouse iNOS, mouse iNOS from cytokine stimulated RAW 264.7 cells.
Tested applicationsSuitable for: IHC-P, WBmore details

Our Abpromise guarantee covers the use of ab3523 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||Use at an assay dependent concentration. PubMed: 28186091|
|WB||1/200 - 1/800. Detects a band of approximately 135 kDa.
Abcam recommends using 5% BSA as the blocking agent.
Note: Regarding using this antibody in WB on mouse lung tissue: "However, iNOS protein was below the limit of detection following any level of hypoxic exposure (positive control was lipopolysaccharide-treated mouse spleen) and using several different antibodies" (from PubMed ID 11686901)
FunctionProduces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In macrophages, NO mediates tumoricidal and bactericidal actions. Also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such COX2.
Tissue specificityExpressed in the liver, retina, bone cells and airway epithelial cells of the lung. Not expressed in the platelets.
Sequence similaritiesBelongs to the NOS family.
Contains 1 FAD-binding FR-type domain.
Contains 1 flavodoxin-like domain.

Observed band size: 140 kDa why is the actual band size different from the predicted?
Additional bands at: 50 kDa, 70 kDa. We are unsure as to the identity of these extra bands.
This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab3523 overnight at 4°C. Antibody binding was detected using Goat anti Rabbit IR680 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx
