- Weitere Details:
- PAPP-A was initially identified as a high molecular mass component in human pregnancy serum. In pregnancy serum PAPP-A exists in a disulfide bound heterotetrameric complex consisting of two 200kD PAPP-A subunits and two 50-90kD subunits of the proform of eosinophil major basic protein (proMBP). The concentration of PAPP-A in serum increases with gestational age, however, in Down’s syndrome pregnancies PAPP-A concentration is markedly reduced in the first trimester. As such, PAPP-A is widely used as an early marker for Down’s syndrome. PAPP-A has also been shown to exist in a homodimeric, 400kD form in unstable atherosclerotic plaques. Increased circulating concentrations of this dimeric PAPP-A are associated with acute coronary syndromes. Applications: Detection of human PAPP-A antigen in FLISA, Western Blot and Western Blot. Recognizes PAPP-A subunit in the heterotetrameric complex in Western Blot. Recognizes proMBP subunit in Western Blot. Recommended Dilution: Optimal dilutions to be determined by the researcher. Matched Pairs: Capture: P6000-80 Detection: P6000-89 Hybridoma: Derived from hybridization of SP2/0 myeloma cells with spleen cells of Balb/c mice immunized with purified human PAPP-A/proMBP complex. Storage and Stability: May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. Allophycocyanin (APC) is light sensitive. Note: Applications are based on unconjugated antibody.
