Anti-Pregnancy associated plasma protein A (human, PAPP-A) BTE 004-09

Mouse monoclonal antibody

BTE 004-09 is specific for native human PAPP-A. Heat and SDS denatured PAPP-A is also recognized, but not acid treated PAPP-A.

Purified human PAPP-A

IgG2b/k

The epitop of BTE 004-09 is different from ABS 006-01 and ABS 006-24. The epitope is located on the PAPP-A subunit of the heterotetramer.

Available in 200 µL and 1 mL size.1 mg/mL +/- 15%. See Certificate of Analysis for details.

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).
