Product Specific Information
This product contains purified recombinant human Pregnancy Associated Plasma Protein-1 (PAPP-A) with an N-terminal hexahistidine tag.
It may be used as a positive control in various immunological assays.
Target Information
Pregnancy-associated plasma protein-A (PAPP-A, Insulin-like growth factor binding protein-4 protease, PAPP-A-proMBP complex) is a large heterotetrameric glycoprotein (~500 kDa) first discovered in serum from pregnant women.
The heterotetramer consists of two PAPP-A subunits and two proMBP subunits.
Low maternal serum levels of PAPP-A during first trimester screening are used as a marker for Down’s syndrome (trisomy 21).
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
