Abstract

UN MEDIO FILTRANTE PARA ELIMINACION SELECTIVA DE LEUCOCITOS DE UNA SUSPENSION DE LOS MISMOS, EL CUAL ESTA FORMADO POR UN ELEMENTO POROSO CON UN DIAMETRO MEDIO DEL PORO DE 1-25(MU)M Y DONDE EL VOLUMEN TOTAL DE LOS POROS DEL ELEMENTO ES 0,40-0,95 ML/ML DEL ELEMENTO Y EL VOLUMEN DE LOS POROS CON DIAMETROS DE 1-30 (MU)M ALCANZA POR LO MENOS EL 90 % DEL VOLUMEN TOTAL DE LOS POROS; Y UN FILTRO EMPACADO CON EL PARA USO EN LA ELIMINACION SELECTIVA DE LOS LEUCOCITOS. EL USO DE ESTE MEDIO SIRVE PARA ELIMINAR LOS LEUCOCITOS HASTA UN CONTENIDO RESIDUAL DE LEUCOCITOS DE 10-4 O MENOS SIN AUMENTAR LA PERDIDA DE PRESION Y PARA REDUCIR EL TAMAÑO DEL FILTRO PARA ELIMINACION SELECTIVA DE LOS LEUCOCITOS.
