Our GST-Trap is a high quality Glutathione S-Transferase (GST)-binding protein coupled to magnetic particles for biochemical analysis of GST fusion proteins and their interacting partners.
Fusion of proteins to Schistosoma japonicum GST is a common technique to increase solubility and expression level of a protein. Furthermore, GST- tagged fusion proteins are often used in protein-protein interaction studies. Both approaches require highly specific tools to isolate and detect GST fusion proteins.
Use GST-Trap for:
- Immunoprecipitation (IP) / Co-IP
- Mass spectrometry
- Enzyme activity measurements
- ChIP/ RIP analysis
Very high binding affinity:
The GST-Trap effectively immunoprecipitates GST-fusion proteins at very low concentrations. See Western Blot (below): Compared to glutathione cellulose, the GST-Trap has a considerably higher affinity.
