A mixture of 12 angiotensins was separated by high-performance liquid chromatography on a weak anion-exchange bonded phase using a triethylammonium acetate buffer and acetonitrile as the eluant. An excellent separation of these compounds was obtained. Recoveries for all 12 were over 90%, as determin

โฆ Synopsis
That the macroporous anion-exchange resin AG MP-1 can be used with HPLC equipment and common aqueous buffers for the chromatography of proteins is shown. The utility of this system is illustrated by the partial purification and complete resolution of the three protein synthesis elongation factors from each other, starting with a crude extract of Escherichia coli. The factors were purified 10- to 30-fold in a yield of 50 to 90% with a single 60-min chromatographic program of increasing NaCl concentration. Other proteins from various biological sources were purified with similar results. Thus, it appears that AG MP-1 is useful, at least in some applications, for the rapid, reproducible, and economical purification of proteins using HPLC equipment.
