Abstract
The present invention relates to a method of preparing bacterial membranous proteoglycans with an action which induces interferon from soluble membranous proteoglycans of a strain of gram-negative bacterium, wherein the soluble membranous proteoglycans of a strain of gram-negative bacterium are hydrolyzed by lysozyme and the proteoglycans with a molecular weight between 200,000 and 400,000 are separated from the hydrolysis product. The products obtained are useful as a medicament.
