New High Performance Columns Allow for High Purity in One Step

GE Healthcare announces the launch of two new high performance columns, MBPTrap™and StrepTrap™.

MBPTrap HP provides convenient affinity purification of recombinant proteins tagged with maltose binding protein (MBP). These columns are prepacked with Dextrin Sepharose High Performance. This robust and stable Sepharose based medium enables elution of target protein in narrow peaks, which minimizes the need for further concentration steps.

StrepTrap HP is supplied ready to use for convenient purification of Strep(II)-tagged recombinant proteins by affinity chromatography. These columns are prepacked with StrepTactin™ Sepharose™ High Performance. The specially engineered coupling of streptavidin to StrepTactin ensures optimized binding properties. This robust and stable Sepharose based medium results in high resolution, sharp concentrated peaks, and reproducible purifications.

Benefits of MBPTrap:

• High purity in one step
• Highly pure protein elutes in narrow peaks
• Mild elution preserves the activity of the target protein
• Tolerates cleaning with sodium hydroxide
• Convenient usage with a syringe, peristaltic pump, or chromatography system

Benefits of StrepTrap:

• High purity in one step
• Sharp, highly concentrated peaks
• Mild elution preserves the activity of the target protein
• Compatible with a wide range of reducing agents, detergents, denaturants, and other additives
• Convenient use with a syringe, peristaltic pump, or chromatography system
