Abstract

EL METODO DE LA INVENCION EMPLEA UNA ENZIMA INMUNOANALIZABLE PARA MEDIR LA CONCENTRACION DE UN ANALIZABLE EN UNA MUESTRA POR DETECCION COLORIMETRICA INDIRECTA. UN RAYO DE LUZ INCIDENTE O UNA PLURALIDAD DE LONGITUDES DE ONDA ES DIRIGIDA DENTRO DE UNA SOLUCION LIQUIDA CONTENIENDO UN ANALIZABLE DE INTERES; LA SOLUCION SERA CAPAZ DE ATENUAR LA CANTIDAD DE LUZ A LA PRIMERA LONGITUD DE ONDA RECIBIDA DE ESTA SOLUCION Y TENDRA ADEMAS LA CAPACIDAD DE INCREMENTAR LA CONCENTRACION DEL ANALIZABLE PRESENTE. UNA SEÑAL LUMINOSA DE LA SOLUCION A LA PRIMERA LONGITUD DE ONDA ES DETECTADA, Y LUZ A LA SEGUNDA LONGITUD DE ONDA, LA CUAL NO SUFRE ATENUACION IMPORTANTE DE SEÑAL, PERO INCREMENTA LA CONCENTRACION DEL ANALIZABLE. LOS NIVELES DE LAS DOS LONGITUDES DE ONDA SON MEDIDOS Y COMPARADOS CON NIVELES CONOCIDOS ACUMULADOS DEL ANALIZABLE PARA DETERMINAR LA CANTIDAD DEL ANALIZABLE EN LA MUESTRA.
