ATW0029 Aptamer to Human Peroxiredoxin-4. Peroxiredoxin-4 is an antioxidant enzyme and belongs to the peroxiredoxin family. The protein is localized to the cytoplasm. Peroxidases of the peroxiredoxin family reduce hydrogen peroxide and alkyl hydroperoxides to water and alcohol with the use of reducing equivalents derived from thiol-containing donor molecules. This protein has been found to play a regulatory role in the activation of the transcription factor NF-kappaB. This aptamer was selected by scientists at Base Pair Biotechnologies using proprietary methods and recombinant Peroxiredoxin-4 Protein, [Novus Biologicals (Cat# NBP1-41141] as a target.
