Abstract

PROCEDIMIENTO DE SEPARACION DE COMPONENTES QUE TIENE BAJA LA ACTIVIDAD BIOLOGICA DE LOS QUE LA TIENE MAYOR. SE SOMETE EL GLUCOSAMINOGLUCANO EN FORMA DE UNA SAL, TAL COMO HEPORINA EN FORMA DE SAL SODICA O CALCICA, EN UNA SOLUCION ACUOSA PARA QUE FLUYA A TRAVES DE UNA MEMBRANA APROPIADA, CON UN CORTE MOLECULAR DE 1.000 A 15.000, PARA ULTRAFILTRACION, HIPERFILTRACION O DIALISIS CON PASO PARCIAL A TRAVES DE LA MEMBRANA, CCON LO QUE LAS FRACCIONES DE BAJA ACTIVIDAD PASAN POR LA MEMBRANA Y LAS FRACCIONES DE MAYOR ACTIVIDAD BIOLOGICA NO PASAN POR ELLA Y SE CONCENTRAN. LOS COMPONENTES CON MAYOR ACTIVIDAD BIOLOGICA SE EMPLEAN COMO ANTICOAGULANTES, ANTILIPERMICOS Y ANTOTROMBOTICOS.
