Abstract
A procedure of isolation of human blood plasma prekallikrein, coagulation factor XII and active fragment beta-XIIa has been developed. This procedure includes the traditional chromatography steps and FPLC. Disc-electrophoresis revealed that the preparations of factor XII and beta-XIIa were homogeneous. Their specific activity was 70.6 U and 2.5 U, respectively. The procedure described is less time consuming and it allows to isolate these factors in the preparative quantities.
