Abstract

UN DISPOSITIVO Y METODO DE ENSAYO PARA DETECTAR UN ANALITICO EN UNA MUESTRA DE LIQUIDO DERIVADO DE UN ESPECIMEN BIOLOGICO (POR EJEMPLO, ORINA O SUERO). EL DISPOSITIVO INCLUYE (A) UNA MEMBRANA DE REACCION POROSA, CON UN RECEPTOR INMOVILIZADO, QUE ES CAPAZ DE ENLAZAR CON LA SUSTANCIA DEL OBJETO, Y (B) UN CUERPO DE MATERIAL ABSORBENTE SITUADO ADYACENTE A LA MEMBRANA DE REACCION POROSA QUE ES CAPAZ DE ABSORBER LA MUESTRA DE LIQUIDO. EL DISPOSITIVO INCLUYE IGUALMENTE UN PUERTO DE FLUIDO ELONGADO, CON UN CIERRE DE FLUIDO DISPUESTO EN LA PERIFERIA DEL PUERTO DE FLUIDO QUE DEFINE UN CIERRE ENTRE UNA PARED DE CONTENEDOR Y UNA MEMBRANA DE REACCION, CON PREFERENCIA, LA MEMBRANA DE REACCION ES UNA BANDA Y LOS MEDIOS DE CIERRE DE FLUIDO SON UN REBORDE CONTINUO QUE SE PROYECTA DESDE LA PARED DEL CONTENEDOR HACIA LA BANDA. EN UNA PRESENTACION, EL RECEPTOR ES UN ANTIGENO, PREFERIBLEMENTE UNA MANCHA DE PROTEINA (POR EJEMPLO, HIV), Y LA SUSTANCIA DEL OBJETO ENLAZABLE ES ANTICUERPO. ANTES DE LA ADICION DEMUESTRA SE APLICA A LA MEMBRANA UNA SOLUCION DE BLOQUEO (PREFERIBLEMENTE 1-2% ENTRE-20 DE AGENTE ACTIVO SUPERFICIALMENTE Y BSA).
