These ETB ELISA kits are immunodetection tools for measuring the levels of ETB in biological samples. ETB is an alias of the human EDNRB gene, which encodes the protein, endothelin receptor type B. Notably, ETB is known to play a role in pathways of aging and the Wnt signaling pathway, among other functions. The EDNRB protein is 442 amino acid residues in length and 49.6 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is reported to be expressed in placental stem villi vessels, but not in cultured placental villi smooth muscle cells. This protein is known to be palmitoylated and glycosylated. Other names for this target antigen include ABCDS and ET-BR.
