Application Abreviews Notes
WB 1/1000. Detects a band of approximately 40 kDa (predicted molecular weight: 41 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
Flow Cyt 1/120.

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



  • Function

    Receptor for prostacyclin (prostaglandin I2 or PGI2). The activity of this receptor is mediated by G(s) proteins which activate adenylate cyclase.
  • Sequence similarities

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

    Palmitoylation of either Cys-308 or Cys-311 is sufficient to maintain functional coupling to G(s) and signaling.
    Isoprenylation does not influence ligand binding but is required for efficient coupling to the effectors adenylyl cyclase and phospholipase C.
  • Cellular localization

    Cell membrane.

  • Immunohistochemical analysis of paraffin-embedded Human endometrium tissue labeling Prostacyclin receptor with ab196653 at 1/250 dilution followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) secondary antibody at 1/500 dilution. Cell membrane staining on Human endometrium is observed. Counter stained with Hematoxylin.

  • Flow cytometric analysis of 2% paraformaldehyde-fixed HepG2 (Human liver hepatocellular carcinoma) cells labeling Prostacyclin receptor with ab196653 at 1/120 dilution (red) compared with a rabbit monoclonal IgG isotype control (black) and an unlabelled control (cells without incubation with primary antibody and secondary antibody; blue). Goat anti rabbit IgG (FITC) at 1/150 dilution was used as the secondary antibody.
