Abstract

UN ENSAYO EN UNA ETAPA DE LA PARTE LIBRE DE UN LIGANDO EN UNA MUESTRA BIOLOGICA INCLUYE LA INCUBACION DE UNA MEZCLA DE LA MUESTRA CON UN ANTICUERPO MARCADO PARA EL LIGANDO Y UN ANALOGO DE LIGANDO QUE COMPITE CON EL LIGANDO PARA ENLAZAR EL ANTICUERPO. EL ENSAYO SE CARACTERIZA POR USAR UN ANTICUERPO MONOCLONAL Y POR ELEGIR UN ANALOGO DE LIGANDO QUE TIENE UNA AFINIDAD POR EL ANTICUERPO INFERIOR A LA DEL LIGANDO. UN ANALOGO DEL LIGANDO INSOLUBILIZADO PREFERIBLEMENTE TIENE UNA AFINIDAD LIGANTE POR EL ANTICUERPO DE 0,01-10 % DE LA DEL LIGANDO. EJEMPLOS DE PARES LIGANDOÑANALOGO DE LIGANDO SON T4/T3 (TIROXINA/TRIYODOTIRONINA); TESTOSTERONA/ETIOCOLANOL; Y T3/T2
