New Products

Millipore announced this week the availability of its ProSep affinity chromatography media designed to facilitate the purification of antibodies. ProSep chromatography media exhibit chemical and mechanical stability over a range of conditions, such as low pH, exposure to detergents and buffers of varying ionic strengths, and permit high flow rates with low back pressure, according to Millipore.

The ProSep media come in three forms: ProSep-vA Ultra media are designed to facilitate purification of antibodies in general; ProSep-G is recommended for purification of antibodies that do not bind efficiently to protein A, such as rat IgGs and human IgG3; ProSep-PB media is designed for the affinity chromatography of a variety of glycoproteins, nucleic acids, and other biomolcules containing 1.2 diol functionality.


Movers & Shakers

Applied Biosystems announced this week that Mark Stevenson has been appointed president of the firm's molecular biology division. He previously served as president of the firm's applied markets division. Stevenson succeeds William Murray, who has resigned due to personal reasons.
