[Prostaglandins and applications in clinical biology].

Pure acetylcholine esterase from Electrophorus Electricus has been covalently coupled to different prostaglandins or thromboxanes. The corresponding conjugates have been tested using microtiter plates with 96 wells coated with a second antibody. The minimal detectable concentrations were 10 pg/ml. We suggest that this procedure which has been extended to non icosanoid molecules may serve as a general technique for enzyme immunoassay.
