FIELD: molecular biology. SUBSTANCE: method of DNA isolation from the human blood involves blood treatment with trimethyloctadecylammonium chloride solution, separation and solubilization of precipitate at high ionic strength following by DNA precipitation from solution with ethanol. Prepared preparation shows absence of RNA and denatured DNA impurities. Spectral properties of preparation confirm the absence of protein impurity. EFFECT: improved method of DNA isolation. 3 dwg, 1 tbl
