Anti-ET3 antibodies enable researchers to detect and measure the ET3 antigen in biological samples. This target is a reported synonym of the EDN3 gene, which encodes endothelin 3. This protein is known to function in axon guidance and cell proliferation, among other biological roles. The human version of ET3 has a canonical amino acid length of 238 residues and a protein mass of 25.5 kilodaltons, although 3 isoforms have been identified. It is reported to be a secreted protein. This target antigen may also be known as ET-3. Immunohistochemistry is the most common application for the ET3 antibodies listed below. ELISA and Western Blot are also common applications.
