Abstract

LA INVENCION SE REFIERE A UN METODO DE FILTRACION VIRICA DE UNA DISOLUCION QUE CONTIENE AL MENOS UNA MACROMOLECULA Y UN CONTENIDO TOTAL DE SAL EN EL RANGO DE 0,2 M HASTA LA SATURACION DE LA DISOLUCION CON LA SAL EN CUESTION. ESTE NUEVO METODO REDUCE EL TIEMPO DE RESIDENCIA Y EL GRADO NECESARIO DE DILUCION DE LA DISOLUCION Y OPTIMIZA EL RENDIMIENTO DE LA FILTRACION VIRICA, PRINCIPALMENTE DE PROTEINAS, POLISACARIDOS Y POLIPEPTIDOS. LA REDUCCION DEL CONTENIDO DE VIRUS ES AL MENOS TAN BUENA QUE LA CONSEGUIDA CON LAS TECNICAS CONVENCIONALES CUANDO EL CONTENIDO TOTAL DE SAL ES PEQUEÑO. LA INVENCION FACILITA LA FILTRACION DE VIRUS CON LA AYUDA DE LA LLAMADA TECNICA DE "TERMINACION" ("DEADEND"), QUE CONSTA DE VARIOS PROCESOS Y OFRECE VENTAJAS ECONOMICAS EN COMPARACION CON LA TECNICA TANGENCIAL DE FILTRACION DE VIRUS UTILIZADA NORMALMENTE. CUANDO SE SOMETE EL FACTOR IX DE LAS PROTEINAS PLASMATICAS A FILTRACION VIRICA, EL RENDIMIENTO DEL PROCESO AUMENTA DE CASI EL 70 % A MAS DEL 95 % AL INCREMENTAR EL CONTENIDO DE SAL DE LA DISOLUCION SEGUN SE PROPONE EN ESTA INVENCION.
