Ferrozine fe2+ binding assay
WebIron binding to a transport protein such as transferrin is dissociated by a weak acidic buffer and a denaturating agent. Dissociated iron is then reduced and forms a chelate with the … WebThe Roche method of iron measurement is a three step process using FerroZine reagent: Fe3+ is liberated from transferrin by acid/detergent, Fe3+ is reduced to Fe2+ by ascorbate, and the reduced iron then reacts with the FerroZine reagent to form a colored complex. The intensity of this final product is directly proportional to the iron
