Our Abpromise guarantee covers the use of ab50914 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 Use a concentration of 1.25 µg/ml. Predicted molecular weight: 63 kDa.Can be blocked with Human Staufen peptide (ab111678). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use at an assay dependent concentration.
ICC/IF Use a concentration of 1 - 5 µg/ml.


  • Function
    Binds double-stranded RNA (regardless of the sequence) and tubulin. May play a role in specific positioning of mRNAs at given sites in the cell by cross-linking cytoskeletal and RNA components, and in stimulating their translation at the site.
  • Tissue specificity
    Widely expressed. Expressed in brain, pancreas, heart, skeletal muscles, liver, lung, kidney and placenta.
  • Sequence similarities
    Contains 3 DRBM (double-stranded RNA-binding) domains.
  • Domain
    One of the DRDB could be involved in RER binding.
    The C-terminal contains the tubulin binding domain (TBD).
  • Cellular localization
    Cytoplasm. Rough endoplasmic reticulum. Localizes exclusively with the rough reticulum endoplasmic.

  • ICC/IF image of ab50914 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab50914, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
