METHOD FOR THE PREPARATION OF SULFATED CELLULOSE MEMBRANES AND SULFATED CELLULOSE MEMBRANES

摘要

The present invention relates to methods for obtaining viral proteins. In particular, the present invention relates to the purification of viral proteins, in particular, of viral membrane proteins from host cells or genetically engineered cells expressing viral proteins, in particular, viral membrane proteins. Specifically, the present invention provides new methods wherein the host cells expressing viral membrane proteins recombinantly or host cells infected with virus and propagating the same are treated with surfactants for membrane solubilization of said host cells.
