A coupled recording assay of cyclic AMP phosphodiesterase activity at and below 1 PM is presented. The method is especially useful in preparative work where speed is more important than high accuracy, but results agree well with a more accurate radioactive assay. Attention is drawn to the fact that,

✦ Synopsis
Adenyl cyclase and 3',5'-AMP1 have been implicated in the hormonal control mechanism of several biochemical reactions (1) and therefore the measurement of 3',5'-AMP in biological material is of interest. In the method of assay used by Rall and Sutherland (2, 3) and later modified by Brown, Clarke, Roux, and Sherman (4), a dog liver extract was used as the source of the relatively inactive liver dephosphophosphorylase and its kinase and of the active liver phosphorylase and its phosphatase. This preparation was shown to carry out the following reaction:

Numerous steatotic livers are discarded as unsuitable for transplantation (TR) because of their poor tolerance of ischemia/ reperfusion (I/R). Cyclic adenosine 3 0 ,5 0 -monophosphate (cAMP)-elevating agents protect against I/R injury both in nonsteatotic livers that have been removed from non-heart
A column chromatogrnphic sy;itrm has been developed for isolation and purification of cAMP and cGMP simultnneously from small tissue samples. In this system, a column of neutral aluminum oxide equilibrated in Tris-HCl buffer, pH 7.5 was used to purify cyclic nucleotides from olhe~ nucleotides in non
