Anti-EWSR1 Antibody

Manufactured by Antibodies.com and distributed through AFMS, this unconjugated polyclonal reagent is raised in rabbit and is designed to detect the endogenous EWSR1 protein (Ewing sarcoma breakpoint region 1 / RNA-binding protein EWS). The antibody is supplied as a 50 µl liquid aliquot at 1 mg/mL in phosphate-buffered saline (without Mg²⁺ and Ca²⁺), pH 7.4, with 150 mM NaCl, 0.02% sodium azide and 50% glycerol as a cryoprotectant. It is purified by antigen-affinity chromatography against the recombinant human EWSR1 immunogen and is recommended for Western blot (WB), with supporting data also available for immunofluorescence (IF). The host species is rabbit, the clonality is polyclonal, the conjugate is unconjugated (no fluorophore or HRP), and the species reactivity covers human, mouse and rat samples, making it suitable for cross-species studies of the EWS oncogene. Vials are shipped on blue ice at 4 °C; for long-term use, aliquot the antibody and store at –20 °C, avoiding repeated freeze/thaw cycles to preserve activity. Researchers working on sarcoma biology, transcription factor research, or RNA-binding protein characterization can rely on Antibodies.com's quality-control documentation and the PhD-level technical support that accompanies the product.
