– TargetMol’s GST Tag Immunomagnetic Beads specifically bind to proteins with the GST tag, which can be used for immunoprecipitation (IP) of proteins, protein complexes, protein-nucleic acid complexes, and other antigens. The GST Tag Immunoprecipitation Kit comes with prepared buffers to provide a relatively better condition for immunoprecipitation and to enhance the stability. This product is suitable for antigen samples from cell lysates, cell culture supernatants, serum, ascites, etc.
