Nitric oxide influences a variety of biological processes including cell proliferation, apoptosis, neurotoxicity and extracellular matrix remodeling. Nitric oxide reacts with superoxide to form peroxynitrite, which in turn nitrates tyrosine residues in proteins. Nitrotyrosine therefore serves as a marker for peroxynitrite action in a variety of disease states and in conditions of cellular damage and oxidative stress.
Our OxiSelect™ Nitrotyrosine Assay Kits provide a simple method to measure the formation of 3-nitrotyrosine in proteins. This assay is available in two formats: a 96-well competitive ELISA and an immunoblotting kit.
