General description
Note: 1 set = 2 x 1 ml.
Synthesized from isoamyl nitrite and hydrogen peroxide. Peroxynitrite (ONOO–) is a strong biological oxidizing agent that reacts with DNA, membrane phospholipids, sulfhydryl groups, and tyrosine. It has been implicated in a variety of patho-physiological conditions including acute respiratory distress syndrome (ARDS), arthritis, atherosclerosis, inflammatory bowel disease, ischemia-reperfusion, N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-mediated neurotoxicity, and septic shock. This product decomposes or isomerizes at pH 8 or less; the half-life at pH 7.5 is ~1.5 s. ε302 nm = 1670M-1cm-1 in 0.1 MNaOH.

Biochem/physiol Actions
Cell permeable: yes
Primary Target
Oxidizing agent that reacts with DNA, membrane phospholipids, sulfhydryl groups, and tyrosine
Oxidizing agent that reacts with DNA, membrane phospholipids, sulfhydryl groups, and tyrosine
Product does not compete with ATP.
Reversible: no
Packaging
Packaged under inert gas
Warning
Toxicity: Oxidizer (K)
Physical form
Supplied in 4.7% NaOH at 160-200 mM.
Preparation Note
Peroxynitrite is soluble in aqueous buffers that have been pre-purged with an inert gas and pre-cooled to 4°C.
Reconstitution
Protect from heat, light, metal ions, and air. Peroxynitrite is unstable; thaw rapidly, dispense into aliquots, purge tubes with an inert gas, and freeze -70°C. Activity decreases ~2% /day at -20°C.

Vascular hypo-responsiveness to vasopressors during septic shock is a challenging problem. This study is to test the hypothesis that reactive nitrogen species (RNS), such as peroxynitrite, are major contributing factors to vascular hypo-responsiveness in septic shock. We hypothesized that adjunct
