FIELD: chemistry.
SUBSTANCE: invention relates to biochemistry. A method of cleaning thrombin solution from infectious particles is provided. Macromolecules are added to the starting thrombin solution. The obtained solution is then passed through a nanofilter to obtain a thrombin solution free from infectious particles. Said macromolecule is not a nonionic surfactant, is different from thrombin and can be selected from a polymer containing at least 3 monomers of sugar, amino acids, glycols, alcohols, lipids or phospholipids. A thrombin-containing solution obtained using said method is also provided.
EFFECT: invention increases efficiency of removing infectious particles from thrombin solution; thrombin output reaches 93% using said method.
