    See all GST primary antibodies
  • Description
    Mouse monoclonal [3G10/1B3] to GST
  • Host species
  • Specificity
    Recognizes Glutathione S-Transferase (GST), a 26-kDa protein encoded by the parasitic helminth Schistosoma japonicum.
  • Tested applications
    Suitable for: WB, IPmore details
  • Species reactivity
    Reacts with: Species independent
  • Immunogen

    Recombinant full length protein within Schistosoma japonicum GST aa 1-218. The exact sequence is proprietary. This is full length GST fusion protein of 425 aa (length of the fusion protein, not GST protein alone). The GST protein is the same GST protein on the pGEX vector ( Schistosoma japonicum).
    Database link: P08515



Our Abpromise guarantee covers the use of ab92 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 26 kDa).
IP Use at an assay dependent dilution.
