Spin Traps

EMPO is a hydrophilic cyclic nitrone analog of the free radical spin trap DMPO.

BMPO is a cell-permeable superior spin trap that captures OH and O 2 •− , forming stable BMPO/OH and • BMPO-OOH adducts.

4-carboxy TEMPO is a nitroxide and spin label.

CYPMPO is a free radical spin trap with excellent trapping capabilities toward hydroxyl and superoxide radicals in biological and chemical systems.

DEPMPO is a nitrone that is used to spin trap reactive O-, N-, S-, and C-centered radicals and allow their characterization when used in association with electron spin resonance.

Nitrosobenzene is a spin trap that has been used in the study of oxidative DNA damage and nitroso-compound-induced respiratory burst in neutrophils.

POBN is a cell permeable, hydrophilic spin trap that can be used to detect free radical adducts in in vitro studies.

PTIO is a nitric oxide-selective capture agent that can react with nitric oxide to form the corresponding • NO 2 and imino nitroxides.

2,2,6,6-Tetramethylpiperidin-1-oxyl (TEMPO) is a stable radical that will react with reactive oxygen species (ROS).
