Our Abpromise guarantee covers the use of ab156173 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 µg/ml. Detects a band of approximately 270 kDa (predicted molecular weight: 210 kDa).
ICC/IF Use a concentration of 5 µg/ml.


  • Function
    Plays a role in RNA-mediated gene silencing by both micro-RNAs (miRNAs) and short interfering RNAs (siRNAs). Required for miRNA-dependent repression of translation and for siRNA-dependent endonucleolytic cleavage of complementary mRNAs by argonaute family proteins.
  • Tissue specificity
  • Sequence similarities
    Belongs to the GW182 family.
    Contains 1 RRM (RNA recognition motif) domain.
  • Cellular localization
    Cytoplasm > P-body. Mammalian P-bodies are also known as GW bodies.

  • ICC/IF image of ab156173 stained MCF7 cells. The cells were 100% methanol 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 (ab156173, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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. This antibody also gave a positive result in 100% methanol fixed (5 min) HeLa and HepG2 cells at 5µg/ml.

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 210 kDa
    Observed band size: 260 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 31 kDa, 50 kDa, 60 kDa, 75 kDa, 98 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 4 minutes

    This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab156173 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
