Antioxidant peptide A TFA（Cat No.:I045855）is a synthetic peptide designed to exhibit strong free radical–scavenging and antioxidative properties. By modulating oxidative stress pathways, it helps protect biomolecules such as proteins, lipids, and DNA from reactive oxygen species (ROS)–induced damage. As the trifluoroacetate (TFA) salt, it offers improved stability and experimental reliability in biochemical and cellular assays. Antioxidant peptide A is widely applied in studies of aging, neurodegeneration, metabolic dysfunction, and inflammation, serving as a useful tool for exploring redox biology and therapeutic strategies targeting oxidative stress.
