Abstract

EL PRESENTE INVENTO SE RELACIONA CON UN ENSAYO RECEPTOR-LIGANTE PARA DETERMINAR LA PRESENCIA O CANTIDAD DE POR LO MENOS UN LIGANTE OBJETIVO, CAPAZ DE COMPETIR CON UN LIGANTE ANALOGO CONJUGADO PARA LIGAR SITIOS DISPONIBLES EN UN RECEPTOR LIGANTE, DICHO LIGANTE CONJUGADO ANALOGO COMPRENDE POR LO MENOS UN LIGANTE ANALOGO ACOPLATO A UN ELEMENTO DE DESARROLLO DE SEÑAL CAPAZ DE EMITIR UNA SEÑAL DETECTABLE, EN UNA MUESTRA FLUIDA DE LA QUE SE SOSPECHA QUE CONTENGA DICHO LIGANTE OBJETIVO, COMPRENDIENDO LOS SIGUIENTES PASOS: A. CONTACTAR DICHA MUESTRA FLUIDA CON UN LIGANTE ANALOGO CONJUGADO Y UN LIGATE RECEPTOR PARA FORMAR UNA MEZCLA DE REACCION, SIENDO LAS CANTIDADES RELATIVAS DE LIGANTE ANALOGO CONJUGADO Y LIGANTE RECEPTOR TALES QUE EN LA AUSENCIA DE LIGANTE OBJETIVO, Y SUBSIGUIENTEMENTE A UNA LIGADURA DE EQUILIBRIO SUBSTANCIAL, PRACTICAMENTE TODO EL LIGANTE ANALOGO CONJUGADO SE UNE AL LIGANTE RECEPTOR; B. DETECTAR EL LIGANTE ANALOGO CONJUGADO NO LIGADO; C. RELACIONAR LA SEÑAL DETECTABLE CON LA PRESENCIA O CANTIDAD DE LIGANTE OBJETIVO EN LA MUESTRA FLUIDA. EN UNA FORMA DE CONSTRUCCION TAMBIEN SE UTILIZA UN MEDIO OPCIONAL PARA REMOVER EL RECEPTOR DE LA MEZCLA DE REACCION. EN FORMATOS DE ENSAYO RELACIONADOS CON EL REIVINDICADO LA ANALITA DE INTERES PUEDE SER UN LIGANTE RECEPTOR O UN LIGANTE.
