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

Application Abreviews Notes
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Detects a band of approximately 34 kDa (predicted molecular weight: 38 kDa).
ICC/IF 1/100 - 1/250.
Flow Cyt 1/10 - 1/100.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Involved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm and may modulate splice site selection. May play a role in HCV RNA replication.
    • Sequence similarities

      Contains 2 RRM (RNA recognition motif) domains.
    • Post-translational

      Arg-194, Arg-206 and Arg-225 are dimethylated, probably to asymmetric dimethylarginine.
    • Cellular localization

      Nucleus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Shuttles continuously between the nucleus and the cytoplasm along with mRNA. Component of ribonucleosomes. In the course of viral infection, colocalizes with HCV NS5B at speckles in the cytoplasm in a HCV-replication dependent manner.
