Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to NADPH oxidase 4. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for NADPH oxidase 4 and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain NADPH oxidase 4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The concentration of NADPH oxidase 4 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
NCBI and Uniprot Product Information
NCBI Description
enzyme involved in the production of reactive oxygen species in vascular smooth muscle cells [RGD, Feb 2006]
Uniprot Description
NOX4: Constitutive NADPH oxidase which generates superoxide intracellularly upon formation of a complex with CYBA/p22phox. Regulates signaling cascades probably through phosphatases inhibition. May function as an oxygen sensor regulating the KCNK3/TASK-1 potassium channel and HIF1A activity. May regulate insulin signaling cascade. May play a role in apoptosis, bone resorption and lipolysaccharide-mediated activation of NFKB. May produce superoxide in the nucleus and play a role in regulating gene expression upon cell stimulation. Isoform 3 is not functional. Isoform 4 displays an increased activity. Isoform 5 and isoform 6 display reduced activity. 7 isoforms of the human protein are produced by alternative splicing.
Protein type: Membrane protein, multi-pass; Oxidoreductase; Nucleolus; EC 1.6.3.-; Membrane protein, integral; Cell cycle regulation

Product Notes
The Rat Nox4 nox4 (Catalog #AAA2882318) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA2882318 ELISA Kit recognizes Rat Nox4. It is sometimes possible for the material contained within the vial of "NADPH oxidase 4, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
