The Separation of Human Globin Chains by Ion-Exchange chromatography on Cm-Sepharose Cl-6B

Abstract
A chromatographic procedure for the separation of human globin chains was described. This method used CM[carboxy methyl]-Sepharose CL-6B as ion-exchanger and NaCl gradients formed in sodium phosphate buffers containing urea and 0.05 M mercaptoethanol to elute the chains. One advantage of this system was that a column, once packed, may be used repeatedly for several chain separations, thus reducing cost and practical work. The resolution was also better than that on CM-cellulose using phosphate buffer gradients.
