Anti-GW182/TNRC6A [4B6] Antibody

This mouse IgG1 monoclonal antibody [4B6] was generated against recombinant protein and recognizes human and rabbit GW182.


  • Reacts with human and rabbit GW182
  • Suitable for Western Blot and Immunofluorscence applications

GW bodies (GWBs) function as storage centers and degradation sites for mRNAs. GW182 is a cytoplasmic marker protein for GWBs that bids to mRNA. GW182 autoantigen, also designated EMSY interactor protein, plays a role in the maintenance and stability of the GWB structures. The GW182 protein has been shown to interact with endogenous argonaute-2 (Ago2), which is also enriched in GWBs. The GW182 protein is found in patients with ataxia, Sjoegren’s syndrome (SS) and sensor neuropathy disease by developing autoantibodies against GWB proteins.
