Peroxynitrite Assay Kit (Cell-based) (ab233468) has been developed to address this unmet need. It provides a sensitive tool to monitor ONOO\u003cbr\u003e\nlevel in living cells. Peroxynitrite Sensor Green is developed as an excellent fluorescent probe, which can specifically react with intercellular ONOO\u003cbr\u003e\nto generate a bright green fluorescent product. This kit can be used in fluorescence imaging and fluorescence microplate reader.\u003cbr\u003e\nOther Notes\u003cbr\u003e\nPeroxynitrite is a strong oxidizing species and a highly active nitrating agent. Peroxynitrite is formed from the reaction between superoxide radicals and nitric oxide generated in cells. It can cause damages to a wide array of biomolecules including proteins, enzymes, lipids and nucleic acids, eventually contributing to cell death. Meanwhile, peroxynitrite can also have protective activities\u003cbr\u003e\nin vivo\u003cbr\u003e\nby contributing to host-defense responses against invading pathogens. Therefore, peroxynitrite is an essential biological oxidant involved in a board range of physiological and pathological processes.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions--20°C, Appropriate long-term storage conditions--20°C, Storage information--20°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nPeroxynitrite is a reactive nitrogen species with a significant role in cellular signaling. It forms rapidly through the reaction of nitric oxide (NO) and superoxide (O2-) making it a critical part of oxidative stress mechanisms. Peroxynitrite is not a protein but a small molecule so it doesn't have a mass like proteins do. Despite being a molecule it has a significant presence in different cell types especially those under oxidative stress conditions. In interactions it often measures cellular responses to changes in redox balance.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPeroxynitrite exerts its influence through oxidizing and nitrating various biological macromolecules. It primarily targets proteins lipids and DNA affecting their function and integrity. Although not part of a complex itself it disrupts cellular complexes like mitochondrial electron transport chain components. This prevention of proper ATP production highlights peroxynitrite's role in energy metabolism disruptions.\u003cbr\u003e\nPathways\u003cbr\u003e\nPeroxynitrite plays a role in inflammatory and apoptotic pathways. It interacts with signaling molecules like NF-kB and caspases mediating cellular stress responses. Peroxynitrite modifies tyrosine residues on proteins leading to altered signaling functions. It closely relates to proteins such as SOD (superoxide dismutase) and iNOS (inducible nitric oxide synthase) due to its formation and effects on cellular processes.\u003cbr\u003e\nPeroxynitrite relates to conditions like neurodegenerative diseases and cardiovascular diseases. Elevated peroxynitrite levels in these diseases indicate oxidative stress and damage to cellular components. During disorders like Alzheimer's disease it interacts with proteins such as amyloid-beta promoting neurotoxic effects. In cardiovascular diseases peroxynitrite interacts with proteins involved in endothelial dysfunction exacerbating disease processes. The presence of antioxidants and scavengers to mitigate peroxynitrite's effects reveal its importance in disease management strategies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843636514985,"sku":"ab233468","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab233468","provider":"Iright","version":"1.0","type":"link"}
