MagZ™ Protein Purification System

MagZ™ Protein Purification System provides a simple, rapid and reliable method for the purification of expressed polyhistidine- or HQ-tagged proteins, which are 99% free of hemoglobin contamination, from rabbit reticulocyte lysate. Based on the use of proprietary, paramagnetic precharged particles, polyhistidine- or HQ-tagged protein can be isolated from 50–500μl of TnT® Coupled Transcription/Translation reactions. Polyhistidine- or HQ-tagged proteins bind to the particles in minutes, while unbound proteins are washed away, and the target protein is eluted with imidazole.

Benefits include minimal hemoglobin (<0.1%) binding to the MagZ™ Binding Particles, no long incubations required, and the ability to further optimize binding/wash and elution conditions for individual polyhistidine- or HQ-tagged proteins.

Note: This product requires the use of a magnetic stand.

For more information, see the Protocols & Applications Guide.
