Product Information

• Name: 4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl free radical
• Brand: Biosynth
• Description: 4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl free radical (ATMPO) is a hydroxyl radical that has been used as a diagnostic agent for oxidative injury. ATMPO reacts with the amino groups on proteins to form an adduct and changes their color from red to blue. This reaction can be used to identify the type of oxidative injury and the degree of injury in cells. ATMPO also interacts with integrin receptors on cell surfaces and causes neuronal death. This effect is reversible when ATMPO is removed from the cells. The molecular weight of this compound is 614 g/mol and it has biocompatible properties because of its long ester linkages and fatty acid chains.
