SELECTIVITY: Supelco's SUPELCOSIL ABZ+Plus columns works like other reverse-phase columns yet provide selectivity for polar and charged compounds.

For academic researchers and scientists who produce proteins on a large scale, separating substances by chromatography has never been easier. New and improved chromatographic support media, along with fully automated, computer-controlled instruments that are becoming increasingly user-friendly, have made it much simpler for even the most analytically challenged life scientist to perform perfect purifications.

LOW-PRESSURE SYSTEM: Bio-Rad's BioLogic LP high-performance system for protein purification. "In many cases, chromatography is used by researchers simply as a tool to get at a particular protein" or other biological molecule, says Tom Pritchett, principal scientist for proteins at Beckman Instruments Inc., a major supplier of chromatography instruments based in Fullerton, Calif. "The growth of the biotechnology industry, however, has led to a large number of companies involved in the production of biopharmaceutical agents. For scientists involved ...
