Abstract
An aqueous solution containing thrombin is heated in the presence of at least one stabilizer selected from various sugars to thereby inactivate viruses possibly contaminating said thrombin. According to this process, the inactivation of the contaminating viruses can be achieved while stably maintaining the thrombin. The stabilizing effect of this process can be further enhanced by using an amino acid as a stabilizer in combination with the sugar.
