WB Use a concentration of 1 µg/ml. Detects a band of approximately 46 kDa (predicted molecular weight: 48 kDa).


  • FunctionReceptor for endothelin-1. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. The rank order of binding affinities for ET-A is: ET1 > ET2 >> ET3.
  • Tissue specificityIsoform 1, isoform 3 and isoform 4 are expressed in a variety of tissues, with highest levels in the aorta and cerebellum, followed by lung, atrium and cerebral cortex, lower levels in the placenta, kidney, adrenal gland, duodenum, colon, ventricle and liver but no expression in umbilical vein endothelial cells. Within the placenta, isoform 1, isoform 2, isoform 3 and isoform 4 are expressed in the villi and stem villi vessels.
  • Sequence similaritiesBelongs to the G-protein coupled receptor 1 family. Endothelin receptor subfamily. EDNRA sub-subfamily.
  • Cellular localizationCell membrane.

  • All lanes : Anti-Endothelin A Receptor antibody (ab85163) at 1 µg/ml

    Lane 1 : Brain (Rat) Tissue Lysate
    Lane 2 : Cerebellum Rat Tissue Lysate

    Lysates/proteins at 10 µg per lane.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 48 kDa
    Observed band size : 46 kDa (why is the actual band size different from the predicted?)

    Exposure time : 20 minutes
    The band observed at 46 kDa could potentially be a cleaved form of Rat Endothelin-1 receptor precursor, as the target protein contains a 20 amino acid signal peptide, which when removed gives an expected molecular weight of 46 kDa.
  • All lanes : Anti-Endothelin A Receptor antibody (ab85163) at 1/250 dilution (in 5% BSA + TBS + 0.1% Tween20 for 12 hours at 4°C)

    Lane 1 : Whole tissue lysate of rat lung
    Lane 2 : Whole tissue lysate of rat lung

    Lysates/proteins at 40 µg per lane.

    An HRP-conjugated Goat anti-rabbit IgG polyclonal at 1/1000 dilution
    Developed using the ECL technique

    Performed under non-reducing conditions.

    Predicted band size : 48 kDa
    Observed band size : 48 kDa

    Exposure time : 30 seconds
