Mouse monoclonal antibody
ABS 006-24 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
IgG1/k
The epitope of ABS 006-24 is different from BTE 004-09 and ABS 006-01. 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).
ELISA BTE 004-09 as coating antibody and biotinylated ABS 006-24 as detection antibody is a good combination for sandwich ELISA.
WB ABS 006-24 only detecs unreduced PAPP-A in Western Blotting.
IHC ABS 006-24 gives the strongest singal in IHC compared to ABS 006-01 and BTE 004-09. ?
