Purity: > 95% by SDS-PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.5) containing 20% glycerol, 0.1M NaCl 1mM DTT.. Frataxin, also known as FXN, is an iron binding protein which belongs to FRATAXIN family. It is an anti-apoptotic protein which prevents mitochondrial damage, reactive oxygen species production and act as either an iron chaperone or an iron storage protein. Frataxin is localized to the mitochondrion and regulating mitochondrial iron transport and respiration. Defects in this protein cause Friedreich ataxia. Recombinant Frataxin protein was expressed in E.coli and purified by using conventional chromatography techniques.
