Anti-EWSR1 Antibody

EWSR1 is a multifunctional RNA-binding protein implicated in transcription regulation, mRNA processing, and the chromosomal translocations that drive Ewing sarcoma and related small round cell tumors. This unconjugated rabbit polyclonal IgG reagent is raised against the EWSR1 target and is validated for Western blot and immunofluorescence workflows. It detects endogenous EWSR1 in both human and mouse sample types, supporting comparative oncology studies and translational research into fusion oncoproteins such as EWSR1-FLI1. Supplied by Antibodies.com as a 50 µl vial of polyclonal antibody, this reagent supports laboratory work on sarcoma biology, fusion transcripts in musculoskeletal tumors, and basic RNA-processing mechanisms. The unconjugated format allows flexible pairing with user-selected secondary detection reagents for chromogenic or fluorescent readouts.
