Background

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).

FAQs for Pappalysin-1/PAPP-A Antibody (34580002). (Showing 1 - 2 of 2 FAQs).

1. 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).
   • 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.
2. I would like to know the specific Immunogen sequence used for the generation of this antibody.
   • The exact immunogen sequence is proprietary, however we can tell you that the immunogen sequence that was used to make the PAPP-A antibody falls between amino acids 850-1000 of the full length protein.
