Anti-GST Tag Antibody

A mouse-derived polyclonal reagent from Antibodies.com, raised against glutathione S-transferase, the 26 kDa affinity tag widely fused to recombinant proteins for expression, purification, and detection workflows. Host: Mouse, Clonality: Polyclonal, Isotype: IgG, Conjugate: Unconjugated, Target: GST Tag. The unconjugated format, supplied as 100 µl of ready-to-use reagent in a vial, makes it straightforward to pair with custom secondary labeling chemistries or HRP-conjugated reporters. Validated applications include Western Blot, Immunofluorescence, and Immunoprecipitation, giving labs a single reagent that can confirm recombinant expression in lysates by WB, localize GST-tagged fusion proteins in fixed cells by IF, and pull down interacting partners from IP reactions. Because GST tag antibodies recognize the affinity tag rather than the protein of interest, they offer a consistent detection handle across constructs whenever an anti-GST reagent is included. Polyclonal clonality broadens epitope coverage, which can be valuable when the GST region is partially occluded by a fusion partner. This reagent is intended for research use only and is supported by Antibodies.com as part of their Primary Antibodies portfolio.
