Anti-SAF-A2 antibodies enable researchers to detect and measure the SAF-A2 antigen in biological samples. This target is a reported synonym of the HNRNPUL2 gene, which encodes heterogeneous nuclear ribonucleoprotein U like 2. The human version of SAF-A2 has a canonical amino acid length of 747 residues and a protein mass of 85.1 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
