Isolation and partial characterization of human factor V.

Factor V was isolated from human citrate plasma by very mild purification steps. Cryoprecipitation, fractionation with polyethylene glycol 6000, gel filtration of AcA 44 and adsorption of haptoglobin to immobilized hemoglobin were applied successively, resulting in factor V preparations with a specific activity of 14.5 unit/mg.
