Abstract: La présente invention se rapporte à la détection de ligands qui se lient à des récepteurs d'hormone stéroïde et les activent. Plus particulièrement, la présente invention concerne des kits de test et des procédés de dosage pour l'identification sélective de ligands de récepteurs d'hormones stéroïdes à partir d'un échantillon d'essai. Il est à noter que, les kits de test et les procédés de dosage selon la présente invention sont exempts de cellules, et ne nécessitent pas d'extraits nucléaires performants à fort coût de fabrication. L'invention concerne des kits de test et des procédés de dosage utilisant des polymérases polypeptidiques uniques, telles que l'ARN polymérase T7, liées à une construction rapporteur. L'activité de l'enzyme est inhibée, au lieu d'être activée, par des complexes récepteurs d'hormone stéroïde liés à un ligand qui ne se forment qu'en présence d'un ligand cible. En conséquence, un changement mesuré dans une propriété physique de la construction rapporteur (par exemple, une fluorescence) peut être utilisé pour déterminer la présence d'un ligand cible dans un échantillon à examiner.
