Our Abpromise guarantee covers the use of ab70588 in the following tested applications.

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

Application Abreviews Notes
IHC-P 1/200 - 1/1000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/2000 - 1/10000. Detects a band of approximately 150 kDa (predicted molecular weight: 139 kDa).
IP Use at 1-4 µg/mg of lysate.


  • FunctionFacilitates nuclear export of spliced mRNA by releasing the RNA from the spliceosome.
  • Sequence similaritiesBelongs to the DEAD box helicase family. DEAH subfamily. DDX8/PRP22 sub-subfamily.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
    Contains 1 S1 motif domain.
  • DomainThe RS domain confers a nuclear localization signal, and appears to facilitate the interaction with the spliceosome.
  • Cellular localizationNucleus.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian carcinoma (left) and mouse teratoma (right) tissues labelling DHX8 with ab70588 at 1/200 (1µg/ml). Detection: DAB.
  • All lanes : Anti-DHX8 antibody (ab70588) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg

    Predicted band size : 139 kDa
    Observed band size : 150 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 117 kDa,65 kDa,<30 kDa. We are unsure as to the identity of these extra bands.
  • Immunoprecipitation of DHX8 from HeLa whole cell lysate (1 mg for IP, 20% of IP loaded) using ab70588 at 3 µg/mg lysate for IP and at 1 µg/ml for subsequent WB detection.
    Detection: Chemiluminescence with an exposure time of 30 seconds.
