Application Abreviews Notes
WB 1/2000 - 1/5000. Predicted molecular weight: 20 kDa.Can be blocked with Human RHEB peptide (ab194764).
IHC-P 1/100 - 1/250.

Heat mediated antigen retrieval and use of an HRP/AP polymerized secondary antibody recommended.

ICC 1/100 - 1/250.
Flow Cyt 1/100 - 1/1000.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • Application notes
    Is unsuitable for IP.
  • Target

    • Function
      Stimulates the phosphorylation of S6K1 and EIF4EBP1 through activation of mTORC1 signaling. Activates the protein kinase activity of mTORC1. Has low intrinsic GTPase activity.
    • Tissue specificity
      Ubiquitous. Highest levels observed in skeletal and cardiac muscle.
    • Sequence similarities
      Belongs to the small GTPase superfamily. Rheb family.
    • Post-translational
      Farnesylation is important for efficiently activating mTORC1-mediated signaling.
    • Cellular localization
      Cell membrane.

    • Overlay histogram showing Raji cells stained with ab92313 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab92313, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in Raji cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
