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

Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 70 kDa (predicted molecular weight: 69 kDa).
IP 1/10 - 1/100.
IHC-P 1/250 - 1/500.
Flow Cyt Use at an assay dependent concentration.
ICC/IF 1/100 - 1/250.


  • 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: MCF7 whole cell lysate (20 µg)
    Lane 4: HeLa whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab126730 observed at 69 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab126730 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. Ab126730 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/10000 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.

  • ab126730 staining DDX5 in the human cell line HeLa (Human cervix adenocarcinoma epithelial cell) by flow cytometry. Cells were fixed with 4% paraformaldehyde, permeabilised with 90% methanol and the sample was incubated with the primary antibody at a dilution of 1/200. A goat anti rabbit IgG (Alexa Fluor® 488) at a dilution of 1/2000 was used as the secondary antibody.

    Isoytype control: Rabbit monoclonal IgG (Black) Unlabelled control: Cell without incubation with primary antibody and secondary antibody (Blue).

    Lane 1 : HeLa cell lysate
    Lane 2 : SH-SY5Y cell lysate
    Lane 3 : A431 cell lysate
    Lane 4 : HT29 cell lysate

    Lysates/proteins at 10 µg per lane.

    All lanes : HRP labelled goat anti-rabbit at 1/2000 dilution

    Predicted band size: 69 kDa

  • Immunocytochemistry/Immunofluorescence analysis of SH-SY5Y (human neuroblastoma) cells labelling DDX5 (green) with purified ab126730 at 1/250. Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. ab150077, Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. DAPI (blue) was used as a nuclear counterstain.  

    Secondary Only Control: PBS was used instead of the primary antibody as the negative control.
