Abstract
The comparative study of the antiheparin activity and acute toxicity of the commercial preparation stellin and its homogeneous fractions was carried out. The summary preparation stellin along with a low antiheparin activity possessed a high toxicity explained by the content of ballast proteins of the nonprotamin nature. One of the homogeneous fractions--stellin B had the best antiheparin properties (heparin neutralizing ratio of 8:1 w:w) and a low toxicity due to a high content of arginine residues and a rigid macromolecular structure facilitating the interpolymer interaction with heparin.
