The ETRA ELISA kits listed below utilize specific antibodies for the plate-based assay of ETRA in various samples. ETRA is another term for the EDNRA gene, which encodes the protein, endothelin receptor type A in humans. It has been reported that ETRA plays a role in the Wnt signaling pathway, among other functions. Structurally, the EDNRA protein is 427 amino acid residues in length and 48.7 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include ET-A, ET-A, and ETA.
The detection range for different ETRA ELISA kits can vary, with some assays measuring target concentrations as low as 0.156 ng/mL and as high as 20 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
