    Schistosoma japonicum GST Antibody Product Information
    Immunogen:Recombinant GST protein
    Clone ID:
    Ig Type:Mouse IgG1
    Concentration:
    Endotoxin:
    Formulation:0.2 μm filtered solution in PBS with 5% trehalose
    Preparation:This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Glutathione S-transferase (GST). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography and conjugated with horseradish-peroxidase (HRP).

    Glutathione S-transferase/GST Background

    Genetic engineers have used glutathione S-transferase to create the GST gene fusion system. This system is used to purify and detect proteins of interest. In a GST gene fusion system, the GST sequence is incorporated into an expression vector alongside the gene sequence encoding the protein of interest. Induction of protein expression from the vector's promoter results in expression of a fusion protein: the protein of interest fused to the GST protein. This GST-fusion protein can then be purified from cells via its high affinity for glutathione. GST is commonly used to create fusion proteins. The tag has the size of 220 amino acids (roughly 26 KDa), which, compared to other tags like the myc- or the FLAG-tag, is quite big. However, many commercially-available sources of GST-tagged plasmids include a thrombin domain for cleavage of the GST tag during protein purification.
