Disclosed is a method for detecting a wide variety of compounds each interacting with a target molecule located on a cell membrane in a simple manner and at low cost, which can use a living cell without the need of separating a cell membrane or the like from the cell. Also disclosed is a kit for achieving the method. The method for detecting a compound interacting with a molecule located on a cell membrane comprises the steps of: reacting a cell with a compound having a moiety capable of binding selectively to the molecule located on the cell membrane and a radicalization-promoting moiety; further reacting the cell with a compound having a group capable of being radicalized by the radicalization-promoting moiety and a labeling group; and identifying a compound to which the compound radicalized by the radicalization-promoting moiety is bound.

L'invention concerne un procédé de détection de composés très divers interagissant chacun avec une molécule cible située sur une membrane cellulaire par une technique simple et peu coûteuse, qui peut employer une cellule vivante sans nécessité de séparer une membrane cellulaire ou un élément similaire de la cellule. L'invention concerne également un nécessaire pour mettre en oeuvre le procédé. Le procédé de détection d'un composé interagissant avec une molécule située sur une membrane cellulaire comprend les étapes consistant à : faire réagir une cellule avec un composé comportant un fragment capable de se lier sélectivement à la molécule située sur la membrane cellulaire et un fragment favorisant la radicalisation ; faire réagir ensuite la cellule avec un composé contenant un groupe susceptible d'être radicalisé par le fragment favorisant la radicalisation et un groupe de marquage ; et identifier un composé auquel le composé radicalisé par le fragment favorisant la radicalisation est lié.
