FIELD: biotechnology.
SUBSTANCE: present invention relates to biotechnology. Method for production of influenza virus with monoglycosylated hemagglutinin-antigen (HA-antigen) is disclosed. Method involves cultivation of influenza virus, containing hemagglutinin-antigen in specific pathogen free (SPF) chicken egg with embryo with an effective amount of mannosidase inhibitor, concentration of which is sufficient for inhibiting of α-mannosidase I in the path of N-glycosylation followed by extraction of produced influenza virus. Further contact of extracted influenza virus with endoglycosidase (EndoH) leads to production of influenza virus, having monoglycosylated influenza virus HA-antigen.
EFFECT: disclosed method enables to obtain influenza virus with monoglycosylated hemagglutinin-antigen (HA-antigen) with high yield using specific pathogen free (SPF) chicken eggs with embryo, and can be used for producing monoglycosylated hemagglutinin-antigen in production of vaccines.
