Abstract
DISPOSITIVO Y METODO PARA DETERMINAR LA PRESENCIA DE ANTIGENOS EN UNA MUESTRA, COMPRENDIENDO EL DISPOSITIVO UNA ZONA DE ATRAPAMIENTO QUE CAPTURA ANTICUERPOS UNIDOS A ENZIMAS, PERO NO ANTICUERPOS ENLAZADOS CON PARTICULAS DE TRANSPORTE, Y UNA ZONA DE SUSTRATO QUE REACCIONA CON ANTICUERPOS UNIDOS A ENZIMAS PARA PRODUCIR UNA REACCION INDICATIVA DE ANTICUERPOS. EL METODO COMPRENDE MEZCLAR UNA MUESTRA CON DOS CLASES DE ANTICUERPOS ESPECIFICOS PARA EL ANTIGENO ENSAYADO, PERO REACCIONANTES CON DIFERENTES DOMINIOS DEL ANTIGENO, ESTANDO LOS ANTIGENOS DE LA PRIMERA CLASE ENLAZADOS CON DICHAS PARTICULAS DE TRANSPORTE Y ESTANDO LOS ANTIGENOS DE LA SEGUNDA CLASE UNIDOS A ENZIMAS, ENLAZANDOSE AMBAS CLASES DE ANTICUERPOS CON EL ANTIGENO Y PASANDO A LA ZONA DE SUSTRATO EN QUE SE PRODUCE LA REACCION INDICATIVA DE LA PRESENCIA DE DICHO ANTIGENO. EL INVENTO ES APLICABLE A LA DETECCION DEL EMBARAZO.
