Our Abpromise guarantee covers the use of ab128928 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
WB 1/1000 - 1/10000. Detects a band of approximately 70 kDa (predicted molecular weight: 69 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function

      RNA-dependent ATPase activity. The rate of ATP hydrolysis is highly stimulated by single-stranded RNA. May be involved in pre-mRNA splicing.
    • Sequence similarities

      Belongs to the DEAD box helicase family. DDX5/DBP2 subfamily.
      Contains 1 helicase ATP-binding domain.
      Contains 1 helicase C-terminal domain.
    • Post-translational

      Arg-502 is dimethylated, probably to asymmetric dimethylarginine.
    • Cellular localization

      Nucleus > nucleolus.

    • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
      Lane 2: DDX5 knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)
      Lane 4: MCF7 whole cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab128928 observed at 69 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab128928 was shown to specifically react with DDX5 in wild-type cells as signal was lost in DDX5 knockout cells. Wild-type and DDX5 knockout samples were subjected to SDS-PAGE. Ab128928 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
