Austin, TX- May 14, 2007– SACHEM announced today that they will exhibit at the TIDES conference next week in Las Vegas, Nevada. Dr. Hemant Joshi, Research Scientist, Biotechnology, will be presenting a poster on SACHEM’s new line of displacers for use in displacement chromatography.

The poster titled, New Displacers for the Purification of Peptides by Reversed-Phase Displacement Chromatography, demonstrates the power of SACHEM’s displacers, as well as the power of displacement chromatography. SACHEM recently launched its Propell™ displacers, which offer a simple way to convert ion exchange analytical columns into effective tools for obtaining large quantities (100+ mg) of purified oligonucleotides in a single run. Propell™ displacers are uniquely designed to work effectively in displacement mode yet are still easily removed from chromatography columns.

SACHEM will offer “The Propell™ Challenge at the exhibition booth at TIDES. “The Propell™ Challenge is a game that helps us illustrates the principals of displacement chromatography in a fun way, explains Rosemary Hoffman, Biotechnology Market Manager. The object of the game is to purify oligonucleotides where the contestant is the “displacer and separates all variants from the main components. Top winners of The Propell™ Challenge will be awarded the new Apple Nano iPod.
