Anti-G3BP1 Antibody

This rabbit polyclonal IgG antibody from Antibodies.com recognizes G3BP1 (Ras GTPase-activating protein-binding protein 1), a 52 kDa RNA-binding protein widely used as a marker for cytoplasmic stress granules.

The unconjugated reagent is supplied as 50 µl of polyclonal serum and is validated for Western blot and immunofluorescence workflows on samples of human, mouse, and duck origin.

Researchers studying stress granule assembly, translational control, innate immunity, and viral host–pathogen interactions routinely use anti-G3BP1 to monitor the recruitment of stalled pre-initiation complexes into SGs under conditions such as oxidative stress, heat shock, or sodium arsenite exposure. The polyclonal format increases the chance of recognizing multiple epitopes across the target, which is helpful when tracking post-translational modifications or isoform expression.

For best results, store aliquots frozen in single-use portions to limit freeze-thaw cycles and protect from light.
