The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 35 kDa (predicted molecular weight: 28 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF 1/50 - 1/100.
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function
      Plays a critical role in both constitutive and enhancer-dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3'-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron.
    • Sequence similarities
      Belongs to the splicing factor SR family.
      Contains 2 C3H1-type zinc fingers.
      Contains 1 RRM (RNA recognition motif) domain.
    • Domain
      The C-terminal SR-rich domain is required for interactions with SR proteins and the splicing regulators TRA and TRA2, and the N-terminal domain is required for formation of the U2AF1/U2AF2 heterodimer.
    • Post-translational
      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • Cellular localization
      Nucleus. Nucleus speckle.
