Abstract

A method for activating prothrombin to thrombin is presented which comprises treating an aqueous solution containing prothrombin with polyethylene glycol in the presence or absence of the calcium salt. The method enables conversion of prothrombin to thrombin in the absence of thromboplastin and allows for preparation of thrombin on an industrially large scale from easily available starting materials.
