Sensitive and specific radioimmunoassays have been developed for cyclic adenosine 3', 5'-
monophosphate (cAMP), cyclic guanosine 3', 5'-monophosphate (cGMP), cyclic inosine 3', 5'-
monophosphate (cIMP), and cyclic uridine 3', 5'-monophosphate (cUMP). These assays are …

The details of a radioimmunoassay capable of measuring as 5 pg of prostaglandin A, E, and
F (PGA, PGE, and PGF) in human and rat plasma are described. Plasma samples are
extracted (with 4000 cpm [3H] PGE1 added for calculation of recovery) with an organic …

The effects of extracellular nucleotides and agents which elevate intracellular cyclic
adenosine 3′, 5′-monophosphate (cyclic AMP) concentrations on human lymphocyte
metabolism have been studied. Aminophylline, isoproterenol, and prostaglandins, all of …

We have studied cyclic adenosine 3′, 5′-monophosphate (cyclic AMP) concentrations in
human peripheral blood lymphocytes after stimulation with phytohemagglutinin (PHA),
isoproterenol, prostaglandins, and aminophylline. Purified lymphocytes were obtained by …

Since extracellular adenosine can alter adenylate cyclase activity and cell function in a
variety of tissues, the effect of adenosine on mediator release was studied with isolated rat
mast cells. Adenosine did not alter the rate of spontaneous release, but histamine release …

In an effort to better define the role of βadrenergic blockade in human bronchial asthma,
peripheral blood leukocytes and lymphocytes from individuals with this condition were
studied for possible alterations in cyclic AMP metabolism. Using a previously described …

The depth profile of foraminiferal samples according to their states of preservation (Fig. 2C) suggests
that in the tropical region there is a zone be- tween depths of 3 and 4 km below which foraminiferal
shells dissolve markedly (14). The occurrence of well- preserved samples below this zone is …

A sensitive, specific, and relatively simple immunoassay permitting measurement of
pharmacological levels of digitoxin in human serum has been developed. The assay
involves binding of 125I-labeled tyrosine-digitoxigenin (specific activity> 400 mc/mg) by …
