特徴

• PAPP A (PAPP-A, Insulin-like growth factor binding protein-4 protease, PAPP-A-proMBP complex) was originally isolated from pregnancy serum as heterotetrameric protein complex with molecular weight approximately 500kD, consisting of two PAPP A subunits disulfide-linked with two subunits of the proform of eosinophil major basic protein (proMBP).
• In such a complex proMBP functions as an inhibitor of PAPP A proteinase activity.
• PAPP A is widely used as a marker of some pathologies during pregnancy.
• Low maternal serum levels of PAPP-A in first trimester biochemical screening is used as a marker of Down’s syndrome (Trisomy 21).
• Applications:Suitable for use in the detection of human PAPP-A antigen in ELISA and Western Blot.
• Other applications have not been tested.
• Recommended Dilution:Optimal dilutions to be determined by the researcher.
• Matched Pairs:Capture: Detection:P6000-82 P6000-80 P6000-82 P6000-81P6000-81 P6000-82
