METHOD OF PREPARING THYMUS POLYPEPTIDES FOR ANTIBACTERIAL RESISTANCE ENHANCEMENT

摘要

FIELD: biochemistry, biologically active peptides. SUBSTANCE: invention ensures to isolate polypeptides showing the increased activity of components acting on macrophage link of immune system. Method of preparing thymus polypeptides is carried out by thymus tissue fractionation in salt solutions and organic solvents followed by ultrafiltration and gel-chromatography. Peptide fractions are isolated by high-pressure gel-chromatography and thymus peptide components of molecular mass 3500-15000 Da and pI = 3.5-5.1 are obtained. EFFECT: improved method of preparing. 1 tblv
