Cyclic 3',5'-adenosine monophosphate level and adenylate cyclase activity in human blood platelets during storage in ACD solution.

The level of cyclic 3',5'-adenosine monophosphate (cAMP) in human platelets and the activity of platelet adenylate cyclase in response to prostaglandin E1 stimulation do not change during two days storage at room temperature in ACD solution. However, the level of cyclic AMP is lower in platelets stored in ACD solution than in platelets from blood anticoagulated by ethylenediamine tetra-acetic acid.
