A radioimmunoassay for plasma androstenedione using 125I tracer.
A radioimmunoassay for plasma androst-4-en-3,17-dione is described using ether extracts of plasma and 125I radioligand. The reagent is easily prepared by an established radiochemical method from androst-4-en-3,17-dione-6 beta-(carboxymethyl) thioether and 125I-histamine.
