Product nameAnti-iNOS antibody
See all iNOS primary antibodies -
DescriptionRabbit polyclonal to iNOS
-
Host speciesRabbit
-
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.

| 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) |
Target
-
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. - Information by UniProt

Western blot - Anti-iNOS antibody (ab3523)All lanes : Anti-iNOS antibody (ab3523) at 1/500 dilution
Lane 1 : iNOS Overexpression Lysate (Human)
Lane 2 : Raw264.7 Whole Cell Lysate
Lane 3 : Raw264.7 Whole Cell Lysate (LPS stimulated)
Lysates/proteins at 20 µg per lane.
Secondary

Performed under reducing conditions.
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
