Background: Pappalysin-1/PAPP-A

PAPP A was originally isolated from pregnancy serum as heterotetrameric protein complex with molecular weight approximately 500 kDa, consisting of two PAPP A subunits disulfide-linked with two subunits of the proform of eosinophil major basic protein (proMBP). In such a complex proMBP functions as an inhibitor of PAPP A proteinase activity. PAPP A is widely used as a marker of some pathologies during pregnancy. Reduced level of PAPP A in pregnancy blood in the first trimester is associated with fetal Down syndrome. PAPP A is considered as one of the best biochemical markers in early pregnancy used to screen for Down syndrome during the first trimester (Wald, N. J. et al).

Showing  1 - 1 的 1 FAQ Showing All

    • Q: I am highly interested to use couple of Anti-PAPP-A antibodies from your reputed companies for my research work. I have got the information regarding the immunogen used to generate these antibodies, however could not get any information regarding the specific amino acids/epitope to which your Anti-PAPP-A Antibodies binds with the antigen (PAPP-A).
      A: Unfortunately, none of our PAPP A antibodies have been epitope mapped. Many of them have also been generated against full-length PAPP A, so there are many potential binding sites.
