Replaces Prod. #: BML-CN262

Water soluble and stable nitric oxide radical scavenger that shows in chemical and biological systems antagonistic action against the free nitric oxide radical (NO·). The inhibitory effects were almost 2-fold stronger than those of NMMA (Prod. No. ALX-106-001) and NOARG (Prod. No. ALX-105-001). Reacts with nitric oxide in a stoichometric manner. Can be used for an improved detection of nitric oxide in activated macrophage cultures in combination with the Griess reagent (Prod. No. ALX-400-004). Protects against endotoxin shock.
