Detection of Human EDNRB/Endothelin R Type B by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected or transfected with human EDNRB/Endothelin R Type B. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human EDNRB/ Endothelin R Type B Monoclonal Antibody (Catalog # MAB4496) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for EDNRB/Endothelin R Type B at approximately 77 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of EDNRB in HEK293 Human Cell Line Transfected with Human EDNRB and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with (A) human EDNRB or (B) irrelevant protein, and eGFP was stained with Mouse Anti-Human EDNRB Monoclonal Antibody (Catalog # MAB4496) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). Quadrant markers were set based on Mouse IgG2A Isotype Control (Catalog # MAB003). View our protocol for Staining Membrane-associated Proteins.
EDNRB/Endothelin R Type B in Human Placenta. EDNRB/Endothelin R Type B was detected in immersion fixed paraffin-embedded sections of human placenta using Mouse Anti-Human EDNRB/Endothelin R Type B Monoclonal Antibody (Catalog # MAB4496) at 1.7 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to smooth muscle.

Background: EDNRB/Endothelin R Type B
EDNRB (Endothelin Receptor Type B) is a 50-55 kDa member of the beta-family of rhodopsin receptors. It binds endothelin 1, 2 and 3, and is found on endothelial cells where it mediates vasodilation. Mature human EDNRB is a 7-transmembrane glycoprotein that is 416 amino acids (aa) in length. It contains a 75 aa N-terminal extracellular region (aa 27-101), and a 44 aa C-terminal cytoplasmic domain. There are three EDNRB variants that affect aa 27-101. One shows a 90 aa N-terminal extension, a second shows the same 90 aa N-terminal substitution coupled with a deletion of aa 268-398, and a third shows proteolytic cleavage between Arg64‑Ser65. Over aa 27-101, human EDNRB shares 67% and 97% aa identity with mouse and canine EDNRB, respectively.
