SACHEM's Displacers Featured in American Biotechnology Laboratory Magazine
Expell(TM) displacers provide rapid protein purification with displacement chromatography.
Austin, TX (PRWEB) March 27, 2008 -- SACHEM's Expell™ displacers are featured in the February issue of American Biotechnology Laboratory. The article is titled 'Displacement Chromatography for Rapid Protein Purification in the Laboratory.'
The article outlines the benefits of using commercial displacers, such as SACHEM's Expell™ to obtain efficient protein separations at very high loadings. Expell™ displacers offer a simple way to convert analytical chromatography columns into effective tools for obtaining 100 mg quantities of purified proteins in a single run. Barry Haymore, Director, New Technology Development and co-author says, "The process turns analytical columns into serious preparative tools and is simple enough to use every day."
Rosemary Hoffman, Director, Biotechnology Solutions Group and co-author states, "Scientists involved with the preparation and purification of material for toxicology and early-stage clinical trials will often find displacement chromatography superior to FLASH and normal elution chromatography."
Protein and peptide purification in the laboratory typically requires several time and labor intensive steps. Displacement chromatography (DC) provides a rapid and convenient process for purification on the 100 mg/run scale. DC purification can be run with commonly available HLPC instrumentation equipped with a large-volume sample loop and fraction collector. Commercially available high purity displacers simplify the entire process. The final product is obtained more quickly and more concentrated than elution chromatography.
