GST Pull-Down Service

GST fusion protein pull-down technology (GST pull-down) utilizes the affinity of GST to glutathione (GSH)-coupled beads, and combines the GST fusion protein with glutathione-coupled beads, and removes the protein that interacts with the GST fusion protein is purified from the mixed solution. This method can identify unknown proteins that interact with known proteins, and can also identify whether there is an interaction between two known proteins. The successful application of GST pull-down depends on whether there are enough soluble GST recombinant fusion proteins. Now, CD BioSciences can provide you with professional GST pull-down service. If you have any needs in this regard, please feel free to contact us.
