Anti-U2AF2 Antibody

Generated in rabbit and supplied by Antibodies.com as an unconjugated polyclonal reagent, this antibody recognizes U2AF2 (U2 small nuclear RNA auxiliary factor 2), a conserved splicing factor that binds the polypyrimidine tract upstream of the 3' splice site during pre-mRNA processing and is widely used as a marker of spliceosome assembly in mammalian cells. Each vial contains 100 µl of antibody at approximately 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant; the reagent should be stored at -20 °C in single-use aliquots to limit freeze-thaw cycles. Validated applications listed on the product datasheet include Western blot, immunohistochemistry, and immunofluorescence, and the antibody has been confirmed to react with human, mouse, and rat samples, supporting cross-species studies of constitutive and alternative splicing in cell biology and disease-relevant research use only workflows.
