Abstract
FIELD: virology, biotechnology. SUBSTANCE: virus-containing suspension is treated with precipitating substance - polyethylenepolyamine (molecular mass is 16000 Da) which is added at the final concentration 0.05-0.2% followed by deposit separation and its resuspending in required volume. Obtained concentrates retain activity at 4-8 C. Method is used for virus concentration for making agents used for prophylaxis and diagnosis of viral infections. EFFECT: improved method of virus concentration. 5 tbl
