An antiserum was raised in rabbits using 5,6-dihydro prostacyclin, a stable analogue of prostacyclin, as the hapten, conjugated to bovine serum albumin. When added to platelet rich plasma the antiserum neutralised the inhibitory activity of prostacyclin, prostaglandin E1 and D2. The amount of antiserum required to neutralise completely a dose of prostacyclin giving 90-95% inhibition of ADP induced aggregation was 10-30 times less than that required for the other two prostaglandins. Small amounts of antiserum prevented the inhibitory activity of prostacyclin generated from endothelial cells in platelet rich plasma.
