Human NOS2/iNOS ELISA Kit | NOS2/iNOS elisa kit
Human NOS2/iNOS (Nitric Oxide Synthase 2, Inducible) ELISA Kit
Typical Testing Data/Standard Curve (for reference only)
Principle of the Assay: This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been precoated with an antibody specific to Human NOS2/iNOS. Standards or samples are added to appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibodies specific for Human NOS2/iNOS and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. After incubation, free components are washed away. Then the Substrate Reagent is added to each well, only those wells that contain Human NOS2/iNOS, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction will be terminated by adding Stop Solution and appears yellow in color. The optical density (OD) can be measured with spectrophotometry at a wavelength of 450 nm +/- 2 nm. The OD value is proportional to the concentration of Human NOS2/iNOS. The concentration of Human NOS2/iNOS in samples can be calculated by comparing the OD of the samples with the standard curve.
NCBI and Uniprot Product Information
NCBI Description
Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. This gene encodes a nitric oxide synthase which is expressed in liver and is inducible by a combination of lipopolysaccharide and certain cytokines. Three related pseudogenes are located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]
Uniprot Description
iNOS: Produces 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. Homodimer. Binds SLC9A3R1. By endotoxins and cytokines. Induced by IFNG/IFN-gamma acting synergistically with bacterial lipopolysaccharides (LPS), TNF or IL1B/interleukin-1 beta. Expressed in the liver, retina, bone cells and airway epithelial cells of the lung. Not expressed in the platelets. Regulated by calcium/calmodulin. Aspirin inhibits expression and function of this enzyme and effects may be exerted at the level of translational/post-translational modification and directly on the catalytic activity. Belongs to the NOS family. 2 isoforms of the human protein are produced by alternative splicing.
