title: [Purification of prothrombin in Nitschmann fraction III by membrane radial column ion-exchange liquid chromatography].
abstract: A method is described for the purification of human prothrombin complex concentrate (PCC) from Nitschmann fraction III by membrane radial column ion-exchange chromatography, which allows large sample volumes to be processed at low operation pressure. The Nitschmann fraction III (15 g) was mixed with 1,000 mL 0.06 mol/L Tris-HCl(pH 7.5). The centrifuged supernatant(10,000 r/min, 15 min, 20 degrees C) was applied onto a DEAE ion-exchange liquid chromatographic column(XK-16 DEAE fast flow Sepharose and DEAE membrane radical column chromatography) with almost the same excellent separation efficiency. The parameters of sample flow rate, elution flow rate and sample capacity were optimized.
