Abstract

UN METODO DE INMUNOANALISIS QUE COMPRENDE LA APLICACION DE UNA SOLUCION ACUOSA QUE CONTIENE EL ANTIGENO DEL ANALITO A UN EXTREMO DE UN DISPOSITIVO DE TIRA DE PRUEBAS CON MULTIPLES ZONAS (10) TAL QUE LA SOLUCION SE MUEVA A LO LARGO DE LA TIRA (10) POR ACCION CAPILAR. LAS ZONAS ESTAN DISPUESTAS PARA QUE LA SOLUCION (A) PRIMERO CONTACTE Y RECONSTITUYA UN COMPONENTE ETIQUETADO SECO DIFUSIBLE QUE COMPRENDE ORO COLOIDAL CONJUGADO CON EL ANTICUERPO ESPECIFICO PARA DICHO ANTIGENO DE ANALITO (20) Y, A CONTINUACION, B) CONTACTE Y RECONSTITUYA UN SEGUNDO ANTICUERPO BIOESTAÑADO DIFUSIBLE SECO ESPECIFICO RESPECTO A DICHO ANTIGENO DE ANALITO (18) DE TAL FORMA QUE SE FORME UN PRODUCTO DE REACCION TIPO "EMPAREDADO" DIFUSIBLE DISPERSO. EL PRODUCTO DE REACCION SE DIFUNDE A LO LARGO DE LA TIRA (10) CON LA SOLUCION Y EN UNA ZONA QUE CONTIENE UN COMPONENTE DE CAPTURA FORMADO POR UN COMPLEJO DE LATEX Y AVIDINA (22) CUYA AVIDINA RECOGE EL PRODUCTO DE REACCION POR MEDIO DE LA REACCION CON SU SISTEMA DE BIOESTAÑO.DE ESTA FORMA, SE RECOGEN Y SE CONCENTRAN LAS PARTICULAS DE ORO EN LA ZONA DE DETECCION (22) PARA LA DETERMINACION VISUAL.
