Datasheets
  • ETBR Antibody (C-5) is a mouse monoclonal IgM κ provided at 200 µg/ml
  • specific for an epitope mapping between amino acids 232-255 of ETBR of mouse origin
  • recommended for detection of ETBR of mouse and rat origin by WB, IP, IF and ELISA
  • Anti-ETBR Antibody (C-5) is available conjugated to agarose for IP; HRP for WB, IHC(P) and ELISA; and to either phycoerythrin or FITC for IF, IHC(P) and FCM
  • also available conjugated to Alexa Fluor® 488, Alexa Fluor® 546, Alexa Fluor® 594 or Alexa Fluor® 647 for WB (RGB), IF, IHC(P) and FCM, and for use with RGB fluorescent imaging systems, such as iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • also available conjugated to Alexa Fluor® 680 or Alexa Fluor® 790 for WB (NIR), IF and FCM; for use with Near-Infrared (NIR) detection systems, such as LI-COR®Odyssey®, iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • m-IgGκ BP-HRP is the preferred secondary detection reagent for ETBR Antibody (C-5) for WB applications. This reagent is now offered in a bundle with ETBR Antibody (C-5) (see ordering information below). For additional m-IgGκ BP conjugates see our complete list of Mouse IgG Binding Proteins.

    ETBR Antibody (C-5) is a mouse monoclonal IgM antibody that detects Endothelin receptor B (ETBR) of mouse and rat origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). ETBR (C-5) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Endothelin receptor B, also known as EDNRB, ETB, ETRB, HSCR, and HSCR2, is a crucial member of the guanine-binding, regulatory protein-coupled receptor family, with three known isoforms: isoform 1, isoform 2, and δ 3. ETBR plays a significant role in regulating sodium excretion and glomerular filtration rate (GFR), which are vital for maintaining fluid balance and blood pressure homeostasis. ETBR is predominantly expressed in various tissues, including the lung, kidney, placenta, skeletal muscle, and stem villi vessels, highlighting its importance in both developmental and physiological processes. ETBR is involved in the normal development of neural crest-derived cell lineages, such as epidermal melanocytes and enteric neurons, which are essential for proper organ function and development. Dysfunction or deficiency of ETBR can lead to severe health issues, including early onset kidney dysfunction characterized by reduced sodium excretion and decreased GFR, as well as congenital conditions like Hirschsprung′s disease Type 2, which is linked to mutations in the ETBR gene.
