Anti-PAB2 antibodies enable researchers to detect and measure the PAB2 antigen in biological samples. This target is a reported synonym of the PABPN1 gene, which encodes poly(A) binding protein nuclear 1. This protein is known to function in the cellular response to lipopolysaccharides and MAPK cascade signaling pathways, among other biological roles. The human version of PAB2 has a canonical amino acid length of 306 residues and a protein mass of 32.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. This target antigen may also be known as OPMD. Indicated applications for PAB2 antibodies listed below include ELISA, Western Blot, and Immunoprecipitation.
