Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO PARA LA SEPARACION POR DIALISIS DE SUSTANCIAS LIGADAS A PROTEINAS (PBS) Y, SI ESTAN PRESENTES, SUSTANCIAS SOLUBLES EN AGUA, DE UN LIQUIDO QUE CONTIENE PROTEINAS (A), POR EJEMPLO, SANGRE O PLASMA CON DICHAS SUSTANCIAS, USANDO UNA MEMBRANA ESPECIAL SEMIPERMEABLE Y UN LIQUIDO DIALIZADO (B) GRACIAS A QUE LA PROTEINA TIENE UN FUNCION DE ACEPTACION PARA LAS PBS DEL LIQUIDO. LA MEMBRANA UTIL PARA ESTE METODO TIENE QUE APORTAR UNA ESTRUCTURA POROSA EN FORMA DE TUNEL SOBRE EL LADO DEL LIQUIDO (A) Y UNA ESTRUCTURA DE ABSORCION Y PORTADORA SOBRE EL LADO DEL LIQUIDO DIALIZADO (B). UNA O AMBAS CARAS DE LA MEMBRANA, POR EJEMPLO EL LADO DEL LIQUIDO QUE CONTIENE PROTEINAS (A) Y EL LADO DEL LIQUIDO DIALIZADO (B) DE LA MEMBRANA, ESTAN RECUBIERTAS DE UNA PROTEINA QUE TIENE UNA FUNCION DE ACEPTACION DE PBS. EL LIQUIDO DIALIZADO (B) QUE CONTIENE PBS OBTENIDO DESPUES DE LA DIALISIS PUEDE ENTONCES SER PURIFICADO A BASE DE PASARLO A TRAVES DE UN DIALIZADOR CONVENCIONALDE CARA A RETIRAR LA SUSTANCIAS SOLUBLES EN AGUA Y DESPUES A TRAVES DE UN ABSORBENTE DE CARBON Y RESINA DE CARA A RETIRAR LAS PBS DE LAS MOLECULAS DEL ACEPTADOR DE PROTEINA. EL LIQUIDO DIALIZADO PURIFICADO (B) OBTENIDO QUE CONTIENE LAS MOLECULAS LIBRES DEL ACEPTADOR DE PROTEINAS SE PUEDE ENTONCES USAR DE NUEVO COMO LIQUIDO DIALIZADO.
