    A novel radioimmunoassay of 7-oxo-DHEA and its physiological levels

  • Original language description

    A novel radioimmunoassay (RIA) of unconjugated 7-oxo-dehydroepiandrosterone (7-oxo-DHEA) in human serum was developed. The method employs polyclonal rabbit antiserum to (19E)-3beta-hydroxy-androst-5-ene-7,17,19-trione 19-O-(carboxymethyloxime):BSA conjugate and a homologous radioiodinated derivative with L-tyrosine methyl ester. The cross reactivity of the antiserum with structurally closest 7-hydroxyepimers of DHEA was lower than 1.7%, with DHEA 0.4%, with all other related steroid less than 0.4%

    Nová metoda radioimunostanovení 7-oxo-DHEA a jeho fyziologické hladiny

  • Czech description

    Bylo vyvinuto nové radioimunologické stanovení (RIA) 7-oxo-dehydroepiandrosteronu (7-oxo-DHEA) v lidském séru. Metoda využívá polyklonální králičí antisérum na konjugát 19-O-(karboxymethyloximu) (19E)-3beta-hydroxy-androst-5-en-7,17,19-trionu s hovězím sérovým albuminem a odpovídající derivát s methyl esterem L-tyrosinu značený radioaktivním jódem. Byla testována jeho zkřížená reaktivita se strukturně blízkými epimery 7-hydroxy-DHEA (menší než 1.7%), s DHEA (0.4%) a ostatními příbuznými steroidy (menšínež 0.4%).
