Radioimmunoassay for pregnancy-associated plasma protein A.
A specific and highly sensitive radioimmunoassay for determination of pregnancy-associated plasma protein A in human serum is described. The minimum detection limit for this protein was 2.9 micrograms/L. The within- and between-assay coefficients of variation were 4.0 and 4.5%, respectively. The circulating protein was detected within 32 days of conception in eight normal pregnancies and within...
متن کاملPregnancy-associated plasma protein A in pregnancy-related gynaecologic emergency.
Serum concentrations of pregnancy-associated plasma protein A (PAPP-A) were measured in patients with pregnancy-related gynaecologic emergencies including ectopic pregnancy (n = 124) and intrauterine abortion (n = 40). The results were compared with those in normal pregnancy (n = 136) and non-pregnant women (n = 460). In ectopic pregnancy and intrauterine abortion, the PAPP-A levels were lower ...
متن کاملEnzyme immunoassay for pregnancy-associated plasma protein-A.
This enzyme immunoassay procedure for pregnancy-associated plasma protein type A involves a "sandwich"-type system in microtitration plates. One can detect 0.27 mg of the protein per liter of serum, with a between-batch CV of 10.2%, and the antiserum used does not cross react with any of the other placentally derived proteins. A reference interval for the last trimester of pregnancy is presente...
متن کاملComparison of pregnancy-associated plasma protein-A, troponin and creatine kinase-MB levels in acute coronary syndrome
Background: Early diagnosis and proper treatment of patient with acute coronary syndrome (ACS) and ischemic heart disease are important in determining prognosis, preventing adverse effects, and may even save lives. In this study, the level of pregnancy-associated plasma protein-A (PAPP-A) in ACS patients was compared with the control group, in addition to cardiac Troponin (cTn) and creatine kin...
متن کاملPregnancy-associated plasma protein-E (PAPP-E).
A full-length cDNA encoding a novel human protein was cloned from placenta cDNA. The corresponding 1542 amino acid protein sequence was termed 'pregnancy-associated plasma protein-E' (PAPP-E) as it shows a 62% homology to the human pregnancy-associated plasma protein-A (PAPP-A) that is a diagnostic marker for trisomies, especially Down syndrome. The conserved domain structure contains five moti...
