Anti-Pw1 antibodies enable researchers to detect and measure the Pw1 antigen in biological samples. This target is a reported synonym of the PEG3 gene, which encodes paternally expressed 3. This protein is known to function in the apoptotic pathway and the regulation of transcription, among other biological roles. The human version of Pw1 has a canonical amino acid length of 1588 residues and a protein mass of 180.8 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include ZKSCAN22 and ZNF904. Indicated applications for Pw1 antibodies listed below include ELISA and Western Blot.
