Anti-DON1 antibodies enable researchers to detect and measure the DON1 antigen in biological samples. This target is a reported synonym of the NRG2 gene, which encodes neuregulin 2. This protein is known to function in intracellular signal transduction and nervous system development, among other biological roles. The human version of DON1 has a canonical amino acid length of 850 residues and a protein mass of 91.7 kilodaltons, although 8 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the cervix, vagina, and bronchus. This target antigen may also be known as HRG2. Indicated applications for DON1 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry.
