Description

Nitric Oxide Synthase 2 (NOS2), also known as inducible NOS (iNOS), contains an N-terminal oxygenase domain and a C-terminal reductase domain, and functions to catalyze the formation of nitric oxide (NO) from L-arginine. NO is a reactive free radical which acts as a biologic messenger with diverse functions throughout the body, such as neurotransmission, antimicrobial, and antitumor activity. NOS2 is involved in inflammatory responses and enhances the synthesis of PGE2 and proinflammatory cytokines such as IL-6 and IL-8. The NOS2 gene is highly expressed in liver and is inducible by a combination of bacterial endotoxins and certain cytokines, including IL-1, IFNγ and TNFα. NOS2 also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such as COX2.

Formulation

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.125 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
