Anti-SEPA antibodies enable researchers to detect and measure the SEPA antigen in biological samples. This target is a reported synonym of the ESPL1 gene, which encodes extra spindle pole bodies like 1, separase. This protein is known to function in the apoptotic pathway and cell division, among other biological roles. The human version of SEPA has a canonical amino acid length of 2120 residues and a protein mass of 233.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the lung and seminal vesicle. Other names for this target antigen include ESP1 and separin. Western Blot is the most common application for the SEPA antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
