[Solubilization of glycoproteins from enveloped viruses by detergents].

The effects of some known ionic and nonionic detergents as well as that of a novel nonionic detergent MESK on various enveloped viruses were investigated. It was found that nonionic detergens (MESK, Triton X-100, octyl-beta-D-glucopyranoside) selectively solubilize glycoproteins of enveloped viruses. The most mild selective action is exerted by the nonionic detergent MESK. Using this detergent, pure preparations of glycoproteins of influenza, parainfluenza, equine Venezuela encephalomyelitis, rabies, vesicular stomatitis and herpes viruses were obtained. The procedure of isolation of purified glycoproteins includes incubation of viral suspensions with MESK, removal of subviral structures by centrifugation and purification of glycoproteins from detergent admixtures by dialysis. Purified glycoproteins retain their native structure and a high biological activity and immunogenicity. MESK seems to be due a perspective tool in the production of subunit vaccines.
