    • Rabbit anti Human U2AF1 antibody recognizes splicing factor U2AF 35 kDa subunit also known as U2 small nuclear RNA auxillary factor 1, U2 small nuclear ribonucleoprotein auxillary factor 35-KD subunit, U2 snRNP auxiliary factor small subunit or U2(RNU2) small nuclear RNA auxiliary factor binding protein.

      The U2AF1 gene belongs to the splicing factor SR family of genes. U2 auxiliary factor, comprising a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. U2AF1 encodes the small subunit which plays a critical role in both constitutive and enhancer-dependent RNA splicing by directly mediating interactions between the large subunit and proteins bound to the enhancers. Alternatively spliced transcript variants encoding different isoforms have been identified (provided by RefSeq, Jul 2008).

      Rabbit anti Human U2AF1 antibody detects a band of 35 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.

    • Lysate Composition
      400μg Raji lysate lyophilized in RIPA buffer.
    • Lysate Reconstitution
      - If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
      - If using BME reconstitute the lyophilized lysate with 180μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 20μl BME.
      Heat at 95°C for 5 minutes. For 10 well mini gels load 25μl. For other gel and comb formats please refer to the PrecisionAb western blotting protocol.
    • Storage
      Store undiluted at -20oC, avoiding repeated freeze thaw cycles.
      Antibody: Store undiluted at -20oC, avoiding repeated freeze thaw cycles.

      Lysate: Store lyophilized lysate at -20°C. After reconstitution aliquot and store at -20°C for up to 3 months or at -80°C for longer term storage.
