MagneGST™ Pull-Down System

The MagneGST™ Pull-Down System is designed for detection of protein interactions between GST-fusion proteins expressed in bacterial lysates and prey proteins expressed in the TnT® Systems. Prey protein synthesized in the TnT® Quick Coupled Transcription/Translation Reaction is captured using bait protein (GST-fusion protein) immobilized on MagneGST™ Particles. Nonspecifically bound proteins are then washed away, and the prey protein is analyzed. Prey proteins can be detected by incorporating radioactively labeled methionine in the TnT® Quick reaction, followed by SDS-PAGE and autoradiography or by incorporating th...
