Anti-E51 antibodies enable researchers to detect and measure the E51 antigen in biological samples. This target is a reported synonym of the PSEN2 gene, which encodes presenilin 2. This protein is known to function in the transport of ions and intracellular signal transduction, among other biological roles. The human version of E51 has a canonical amino acid length of 448 residues and a protein mass of 50.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the ER and Golgi of cells. Other names for this target antigen include AD3L, AD4, and CMD1V. Western Blot is a widely used application for the E51 antibodies listed below. In addition, Immunohistochemistry is also a common application.
