METHOD OF PREPARING PURIFIED INFLUENZA VIRUS BIOMASS Russian patent published in 1996 - IPC

Abstract RU 2057804 C1

FIELD: microbilogical technology. SUBSTANCE: purified biomass of influenza virus is prepared by sorption from virus-containing allantois liquid of ballast proteins. Sorption is carried out by immersion of coal-fibrous sorbent portion in virus-containing liquid. Sorption capacity of sorbent is 900-1000 mg/g by methylene blue. Volume ratio of virus-containing liquid: sorbent = (90-100):1, time contact of sorbent with liquid is 10-15 min. Product can be used in vaccines and viral antigens preparing. EFFECT: increased output of product, high purification degree, simplified method. 3 tbl
