This paper examines the use of wide-pore silica-based hydrophilic ether-bonded phases for the chromatographic separation of proteins under mild elution conditions. In particular, ether phases of the following structure Si-(CH2)3-O-(CH2-CH2-O)n-R, wheren 1, 2, 3 and R methyl, ethyl orn-butyl, have been prepared. These phases can be employed either in high-performance hydrophobic-interaction or size-exclusion chromatography, depending on mobile phase conditions. In the hydrophobic-interaction mode, a gradient of decreasing salt concentration,e.g., from 3Mammonium sulfate (pH 6.0, 25°C), yields sharp peaks with high mass recovery of active proteins. In this mode, retention can be controlled by salt type and concentration, as well as by column temperature. In the size-exclusion mode, use of medium ionic strength,e.g., 0.5Mammonium acetate (pH 6.0) yields linear calibration of log (MW[n]) vs. retention volume. Even at 0.05Msalt concentration, no stationary phase charge effects on protein elution are observed. These bonded-phase columns exhibit good column-to-column reproducibility and constant retention for at least five months of continual use. Examples of the high-performance separation of proteins in both modes are illustrated.
