Anti-SAFA antibodies enable researchers to detect and measure the SAFA antigen in biological samples. This target is a reported synonym of the HNRNPU gene, which encodes heterogeneous nuclear ribonucleoprotein U. This protein is known to function in the cell cycle, among other biological roles. The human version of SAFA has a canonical amino acid length of 825 residues and a protein mass of 90.6 kilodaltons, although 2 isoforms have been identified. It is reported to be widely expressed in many tissue types. Other names for this target antigen include DEE54, EIEE54, and GRIP120. Western Blot is a widely used application for the SAFA antibodies listed below. In addition, ELISA is also a common application.
