• For immunohistochemistry (PFA-fixed): incubate antibody for 30 minutes at room temperature.
• Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA (pH 9.0) for 45 minutes at 95°C, followed by cooling at room temperature for 20 minutes.

Target Information

Pregnancy-associated plasma protein-A (PAPP-A, also known as Insulin-like growth factor binding protein-4 protease or PAPP-A-proMBP complex) is a large heterotetrameric glycoprotein of approximately 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 in first trimester biochemical screening are used as a marker of Down’s syndrome (trisomy 21).
