Details for:  Angiotensin I (PRA) RIA (CT)
Radioimmunoassay of Angiotensin I for the determination of Plasma Renin Activity (PRA) in human plasma. For research use only.

The Angiotensin I RIA serves for the quantitative determination of plasma renin activity (PRA) by the radioimmunoassay of the product of the reaction, angiotensin I.
The generation of angiotensin I is the result of the enzymatic cleavage of the renin substrate, angiotensinogen, in plasma samples in the presence of ACE inhibitor (ACE - Angiotensin-Converting Enzyme), an enzymatic inhibitor that blocks the conversion of angiotensin I to angiotensin II. The immunoassay of angiotensin I is a radioimmunological competition assay. Unknown samples, control, and calibrators are incubated in polyclonal antibody-coated tubes with 125I-labeled angiotensin I as tracer. After incubation, the contents of the tubes are aspirated. The bound radioactivity is then determined in a gamma counter. A standard curve is established and unknown values are determined by interpolation from the standard curve.
