Background: Pappalysin-1/PAPP-A

Pregnancy-associated plasma protein-A (PAPP-A, Insulin-like growth factor binding protein-4 protease, PAPP-A-proMBP complex) is a large heterotetrameric glycoprotein of approximately 500 kDa, which was first discovered in serum from pregnant women. The hetreotetramer consists of two PAPP-A subunits and two proMBP subunits. Low maternal serum levels of PAPP-A in first trimester biochemical screening is used as a marker of Down's syndrome (trisomy 21).

Long Name

Pregnancy-associated Plasma Protein 1

Alternate Names

ASBABP2, DIPLA1, IGFBP-4ase, PAPA, PAPP-A1, PAPPA, Pappalysin1

FAQs for Pappalysin-1/PAPP-A Antibody (PAPP A1-24) - BSA Free

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.
