SNAP is a stable green crystalline S-nitrosothiol compound that mimics the action of nitric oxide in vivo. It has vasodilatory properties and has been shown to relax isolated bovine coronary artery rings by activating soluble gran­u­late cyclase. This reagent also actuates apoptosis in mouse thy­mocytes and has been accounted for reversible inactivation of pro­tein Kinase C. SNAP can be used for calibration of all WPI NO sensors. Call for details. M.W. 220.2, Purity > 98% by NMR or TLC
