Background Information
Protein tags are protein or peptide sequences located either on the C- or N- terminal of the target protein, which facilitates one or several of the following characteristics: solubility, detection, purification, localization and expression. GST (Glutathione S-Transferase) is a widely used protein tag encoded by the Schistosoma japonicum. GST provides both an easily detectable tag and a simple purification process with little effect on the biological function of the protein of interest. Antibodies to GST are useful for checking protein expression both in plaques and on Western blots as well as for immunoaffinity purification of proteins expressed in cells. This antibody recognizes the GST-tag fused to either the N- or C-terminus of targeted proteins.

Reviews
What customers say
Customers report excellent performance for Western Blot and Immunoprecipitation applications. One user achieved clear signal with no background on E. coli lysate at a 1:30,000 dilution. Another provided a detailed WB protocol using a 1:5,000 dilution for GST protein detection on PVDF membranes. A third user confirmed successful use for both IP (1 µl) and WB (1:5,000) in in vitro experiments. Overall, reviewers highlight strong specificity, low background, and reliable detection of GST-tagged proteins across a wide dilution range.
