Bio-Rad Laboratories, Inc. has announced the introduction of its new Profinia™ protein purification system, an automated low pressure liquid chromatography system designed to enable scientists to perform unattended affinity purification and desalting of recombinant tagged proteins.
Optimizing traditional methods of purification for tagged proteins using spin and gravity kits or low pressure chromatography systems is often challenging. The Profinia system does not require special chromatography training or expertise.
“Unlike traditional manual purification such as gravity-flow columns, which can take up to four hours just for the affinity step, the Profinia system’s automated affinity purification and desalting methods can be completed in as little as thirty minutes,” said Eric Larson, Bio Rad Life Science Group’s Chromatography Marketing Manager, Laboratory Separations Division.
According to Company, filling the need for a system that stands between manual kits for purification and sophisticated instrumentation-based methods of separations, the Profinia system represents an automated purification solution for scientists currently using manual affinity kits or for those who want to complement their existing chromatography system with an applications-based device.
The Profinia’s large touch screen guides the user through method selection and sample loading. Purified protein is automatically collected into a single tube, and protein yield and concentration is calculated and displayed on the screen at the end of the run. The system can also be used with optional Profinia software, which displays purification data in real time and allows for publication-quality report generation.
