A radioimmunoassay specific for the direct measurement of dehydroisoandrosterone sulfate
in 0.5 or 1 μl of human serum was developed using an antibody directed against�…

Abstract At pH 4.5, the hydrolysis of 3β-hydroxy-5-androsten-17-one 3-sulfate (DHA-SO 4) to
DHA was complete within 75 min at 120� or 4h at 100�. In the same conditions, the 3α-SO 4�…

In a cross-sectional study, serum dehydroepiandrosterone sulfate (DS) concentrations were
measured in 981 men and 481 women, aged 11-89, yr. The resulting data were�…

In order to determine the contribution of serum dehydroepiandrosterone sulfate (DS) to
estrone (E1) production in normal women and the effect of chronic elevation of the serum DS�…

The 24-h mean plasma concentrations of dehydroisoandrosterone (DHA) and
dehydroisoandrosterone sulfate (DHAS) and the DHA to DHAS ratio were determined in 37�…

A thermospray high-performance liquid chromatography/mass spectrometry method for
determination of serum dehydroepiandrosterone sulfate is described. The steroid was�…

A bolus iv injection of 50 mg dehydroepiandrosterone sulfate (DS) followed by a constant 2-
h infusion of 200 εg DS/min was administered to 5 pregnant patients at term and to 5�…

Dehydroepiandrosterone (D) and dehydroepiandrosterone sulphate (DS) concentrations
were determined by radioimmunoassay in peripheral sera of non-pregnant, pregnant (55�…

Circulating dehydroepiandrosterone sulfate (DS) declines in old age, falling to almost
undetectable levels after the seventh decade. Since an accelerated decrease occurs after�…

We measured serum dehydroepiandrosterone sulfate (DHEA-S) levels by nine different
radioimmunoassay (RIA) methods. Although each method was adequate for determining the�…
