Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function

      Non-specific receptor for endothelin 1, 2, and 3. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.
    • Tissue specificity

      Expressed in placental stem villi vessels, but not in cultured placental villi smooth muscle cells.
    • Involvement in disease

      Defects in EDNRB are a cause of Waardenburg syndrome type 4A (WS4A) [MIM:277580]; also known as Waardenburg-Shah syndrome. WS4A is characterized by the association of Waardenburg features (depigmentation and deafness) and the absence of enteric ganglia in the distal part of the intestine (Hirschsprung disease).
      Defects in EDNRB are the cause of Hirschsprung disease type 2 (HSCR2) [MIM:600155]; also known as aganglionic megacolon (MGC). HSCR2 is a congenital disorder characterized by absence of enteric ganglia along a variable length of the intestine. It is the most common cause of congenital intestinal obstruction. Early symptoms range from complete acute neonatal obstruction, characterized by vomiting, abdominal distention and failure to pass stool, to chronic constipation in the older child.
      Defects in EDNRB are the cause of ABCD syndrome (ABCDS) [MIM:600501]. ABCD syndrome is an autosomal recessive syndrome characterized by albinism, black lock at temporal occipital region, bilateral deafness, aganglionosis of the large intestine and total absence of neurocytes and nerve fibers in the small intestine.
    • Sequence similarities

      Belongs to the G-protein coupled receptor 1 family. Endothelin receptor subfamily. EDNRB sub-subfamily.
    • Post-translational

      Palmitoylation of Cys-402 was confirmed by the palmitoylation of Cys-402 in a deletion mutant lacking both Cys-403 and Cys-405.
    • Cellular localization

      Cell membrane.

    I am happy to confirm that you do not need to permeabilise your cells, since a peptide fom the extracellular region of the Endothelin B Receptor protein was used as immunogen.

    As additional information you can find attached data from Flow cytometric analysis using ab129102. Further, I detail a FC protocol, in case you find it useful:

    FC protocol (extracellular)

    1. Solutions and Reagents

    1.1. 1× PBS

    1.2. Blocking buffer: 3% FBS in 1X PBS

    2 Protocol

    2.1. Collect 1x106 cells/sample.

    2.2. Wash cells twice with blocking buffer.

    2.3. Add primary antibody at appropriate dilution and incubate for 1h at room temperature.

    2.4. Wash twice with blocking buffer and incubate with fluorescent-conjugated secondary antibody for 30 minutes at room temperature in dark.

    2.5. Wash twice with blocking buffer.

    2.6. Re-suspend cells in 1× PBS and transfer to FACS tubes. Analyze on flow cytometry.

    Thank you very much for this information. We are very pleased to hear that you managed to determine the specificity of the anti-Endothelin Receptor B using the blocking peptide.

    Thank you for your inquiry.

    We currently don't determine the specific isotype for our rabbit monoclonal antibodies, and that they are simply known as IgG. We used rabbit IgG as negative control and we are offering the rabbit IgG, which can be used as a negative control for Flow Cytometry and IHC:

    ab37406. ab37407, ab37415

    The exact immunogen sequence used to generate this antibody is commercially sensitive information.

    If you need any further assistance in the future, please do not hesitate to contact me.
