The PAP-alpha ELISA kits listed below are analytical tools for measuring concentrations of PAP-alpha in various samples. PAP-alpha is an alternative name for the human PAPOLA gene, which encodes the protein, poly(A) polymerase alpha. The target protein is a reported polymerase that creates the 3'-poly(A) tail of mRNA's. Structurally, the PAPOLA protein is 745 amino acid residues in length and 82.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. This protein is known to be sumoylated, acetylated and phosphorylated. Other names for this target antigen include PAP, PAP, and PAP-alpha. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
