Abstract Prothrombin complex (P.C.) preparations obtained by batch adsorption onto DEAE-Sephadex are highly enriched in C4. Based on this observation a technique has been elaborated where the P.C. analogue is further submitted to precipitation by ethanol and batch adsorption of impurities on DEAE-Cellulose. Unaltered C4 is obtained in a 2 days process with a yield corresponding to 40 % of the starting material (cryoconcentrate supernatant). 相似文献
