Pall, Genetix, Swiss Proteomics Society


Following its acquisition of Ciphergen’s BioSepra division in November 2004, Pall launched this week a comprehensive line of chromatography sorbents. According to Pall, the sorbents simplify protein separation and purification.

Pall also announced this week the opening of its first two Process Proteomics technologies to rapidly develop multi-step chromatographic purification schemes, which help reduce protein purification cycle time from several months to days.

Genetix announced this week the launch of its QPExpression — a new system that integrates automated colony picking with liquid handling.

According to Genetix, the new system automates the workflow of plasmid transformations, bacterial streaking, colony imaging, picking, tracking and management. The system first plates out up to 96 transformation mixes and spreads cells out to form single colonies. Following overnight incubation, the system automatically acquires images of the clones derived from each transformation reaction through a camera. A user-defined number of colonies is then picked from each construct and dispensed into multiwell plates for sequence verification, protein production, or curation.

The Swiss Proteomics Society announced this week that it has set up a database of proteomics courses available worldwide. The list can be viewed by location at, or by date at
