Anti-PRP22 antibodies enable researchers to detect and measure the PRP22 antigen in biological samples. This target is a reported synonym of the DHX8 gene, which encodes DEAH-box helicase 8. This protein is known to function in RNA splicing, among other biological roles. The human version of PRP22 has a canonical amino acid length of 1220 residues and a protein mass of 139.3 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include DDX8, DDX8, and Dhr2.
