Materials and MethodsApohemoglobin was prepared from human hemoglobin by the method of Teale (1959). Its concentration was determined spectrophotometrically by using E= 0.85 mL mg" 1 cm" 1 at 280 nm in 0.1 M NaOH.Apohemoglobin in0. 2 M phosphate buffer at pH 7.0 was recombined with 1.5 stoichiometric equivalents of Zn-heme dissolved in 0.01 M NaOH. The mixture was left overnight in the cold, and then it was filtered through Sephadex G-25 equilibrated with 0.01 M phosphate buffer at pH 6.4 and absorbed on a CM-cellulose column equilibrated with the same buffer. A gradient elution was performed with equal volumes on 0.01 M phosphate buffer at pH 6.1 and 0.04 phosphate buffer at pH 7.5. The main fraction was collected and stored in the cold, in the dark.
