|Detection of Human EDNRB/Endothelin R Type B by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line, A172 human glioblastoma cell line, and Raji human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human EDNRB/Endothelin R Type B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4496) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for EDNRB/Endothelin R Type B at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.|
|Detection of EDNRB/Endothelin R Type B in A172 Human Cell Line by Flow Cytometry. A172 human glioblastoma cell line was stained with Human EDNRB/Endothelin R Type B Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF4496, filled histogram) or isotype control antibody (Catalog # 5‑001‑A, open histogram), followed by NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010).|
|EDNRB/Endothelin R Type B in A172 Human Cell Line. EDNRB/Endothelin R Type B was detected in immersion fixed A172 human glioblastoma cell line using 10 µg/mL Sheep Anti-Human EDNRB/Endothelin R Type B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4496) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

EDNRB (Endothelin B Receptor) is a 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 sequence identity with mouse and canine EDNRB, respectively.
