Anwendungen & Verwendung

Beschreibung

PTIO is an oxidizing reagent that reacts with nitric oxide to form nitric dioxide and corresponding imino nitroxides. It can be used to assay nitric oxide production when examining nitric oxide synthase inhibitory activity.

Verwenden

PTIO is a nitric oxide (NO) radical scavenger used to inhibit physiological effects of NO.
