Product Specific Information
ABS 006-24-02 detects native Pregnancy-associated plasma protein A (PAPP-A) from human samples. Heat and SDS denatured PAPP-A is also recognized, but not acid treated PAPP-A.
 
ABS 006-24-02 has been successfully used in Western blotting, Immunohistochemistry and ELISA procedures. By Western blot, only unreduced forms of PAPA-A can be detected. In sandwich ELISA the optimal combination was BTE 004-09-02 as coating and biotinylated ABS 006-24-02 as detection. ABS 006-24-02 give the strongest singal in IHC compared to ABS 006-01-02 and BTE 004-09-02.

The ABS 006-24-02 immunogen is purified human PAPP-A.

The epitope of ABS 006-24-02 is different from BTE 004-09-02 and ABS 006-01-02. The epitope is located on the PAPP-A subunit of the heterotetramer.
General Information
Pregnancy-associated plasma protein-A (PAPP-A, Insulin-like growth factor binding protein-4 protease, PAPP-A-proMBP complex) is a large heterottetrameric 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).
