PAPPA ELISA kits are immunoassay tools for the measurement of the protein pappalysin 1, which is encoded by the PAPPA gene in humans. Functionally, this protein is known to be involved in receptor-mediated signaling pathways and proteolysis. The canonical protein structure is reported to have an amino acid length of 1627 residues, a mass of 181 kDa, and is a member of the Peptidase M43B protein family. It is known to be secreted and is notably expressed in placenta and pregnancy serum. The protein has been noted to be post-translationally glycosylated. Other alias names for this target include DIPLA1, IGFBP-4ase, PAPA, PAPPA1, IGF-dependent IGFBP-4 protease, and ASBABP2.
The detection range for different PAPPA ELISA kits can vary, with some assays measuring target concentrations as low as 23.4 pg/mL and as high as 30 µg/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
