- 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 ELISA, 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 for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
