[The use of colloidal gold-labelled antibodies for demonstrating viral antigens].

The principal possibility of using antibodies conjugated with colloid gold for better visualization of viruses, viral antigens, and their immune complexes in electron microscope was studied on the experimental model of HBs-antigen and Venezuelan equine encephalomyelitis virus. The same method was used for the study of the thin structure of influenza A (H1N1) virus hemagglutinins using monoreceptor antisera.
