title: Purification of factor VIII:c coagulant activity from rat liver nonparenchymal cell culture medium by immobilized metal ion affinity chromatography.
abstract: The purification of factor VIII:c coagulant activity on the basis of its affinity for calcium is described. For this purpose, use was made of a recently introduced chelating matrix, i.e., carboxymethylated aspartic acid agarose, coupled with calcium--thereby creating a gel with specificity comparable with biospecific affinity chromatography. In a single step factor VIII:c activity was purified from rat liver nonparenchymal cell culture medium with a purification factor of 85-fold. The material exhibits a single band on polyacrylamide gel electrophoresis.
