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 IHC-P or IP.
  • Target

    • Function

      Receptor for somatostatins-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase.
    • Tissue specificity

      Brain, pituitary and pancreas.
    • Sequence similarities

      Belongs to the G-protein coupled receptor 1 family.
    • Post-translational

      Phosphorylated. Phosphorylation increases upon somatostatin binding.
    • Cellular localization

      Cell membrane. Internalized into endoplasmic vesicles upon somatostatin-stimulation.

    • Overlay histogram showing SHSY-5Y cells stained with ab137026 (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 (ab137026, 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 SHSY-5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
