These PAPPA1 ELISA kits are immunodetection tools for measuring the levels of PAPPA1 in biological samples. PAPPA1 is an alias of the human PAPPA gene, which encodes the protein, pappalysin 1. Notably, PAPPA1 is known to play a role in receptor-mediated signaling pathways and proteolysis, among other functions. The PAPPA protein is described to be 1627 amino acid residues in length and 181 kilodaltons in mass. It is known to be a secreted protein. In terms of tissue specificity, it is notably expressed in placenta and pregnancy serum. This protein is known to be glycosylated. Other names for this target antigen include ASBABP2, DIPLA1, and IGFBP-4ase. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
