Anti-GST Antibody

Supplied as 100 µg of lyophilised powder, this rabbit polyclonal primary antibody from Antibodies.com targets Glutathione S-Transferase (GST) and is validated for detection of the human protein. The unconjugated IgG reagent offers flexibility for downstream labelling, pairing cleanly with secondary antibody conjugates such as HRP, biotin, or fluorophores for Western blot detection, immunohistochemistry, immunofluorescence, and immunoprecipitation workflows.

GST is one of the most widely used affinity tags in recombinant fusion protein expression, so a tag-specific reagent is a practical tool for confirming expression of GST-tagged constructs, pulling down tagged proteins from lysates, or probing blots without needing a target-specific antibody. The polyclonal nature of the reagent increases the likelihood of recognising multiple epitopes on the GST protein, which can be advantageous when working with partially denatured samples, when signal strength is a priority, or when the tag has been fused to a low-abundance partner protein.

The lyophilised format supports long-term storage and convenient reconstitution in the laboratory. After resuspension, the antibody should be handled as a standard IgG preparation; aliquoting is recommended to limit freeze-thaw cycles and preserve binding activity over many experiments. Provided unconjugated, it remains compatible with a broad range of custom labelling chemistries and downstream detection platforms used across protein biochemistry and cell biology research.
