MagneGST Pull-Down System detects protein interactions between GST-fusion proteins expressed in bacterial lysates and prey proteins expressed in the TNT Systems.

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 the supplied non-radioactive methionine in the TNT reaction and detecting by Western blotting with protein-specific antibodies.
