Application
Recommended Usage

ELISA

1:8000

Immunohistochemistry

1:10-1:500

Immunohistochemistry-Paraffin

1:10-1:500

Western Blot

1:100-1:2000
Application Notes
ELISA: In sandwich ELISA the optimal combination is NBP1-05116 used as coating antibody and biotinylated NBP1-05043 used as detection antibody. NBP1-05116 can also be used as detection antibody in sandwich ELISA in combination with a polyclonal antibody towards PAPP-A in coat. WB: NBP1-05116 detect both reduced and unreduced PAPP-A in Western Blotting, though reaction to unreduced is less than that of NBP2-21614 and NBP1-05043. IHC: NBP1-05116 can be used in IHC.

Background: Pappalysin-1/PAPP-A

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).

Long Name

Pregnancy-associated Plasma Protein 1

Alternate Names
