A method for purifying hemoglobin, mixed with other proteins is described, wherein the mixture is contacted with an ion exchange matrix so that the hemoglobin is adsorbed to it. The matrix is washed to remove unadsorbed components, and the hemoglobin is then selectively eluted using a ligand which specifically binds the hemoglobin causing it to desorb from the matrix. The method can also be used to effect reduction of methemoglobin to hemoglobin on an ion exchange matrix followed by selective elution to achieve purification. The method can also be used to purify methemoglobin.
