Abstract: The present application discloses retrovirus-derived vectors in which the retroviral envelope glycoprotein has been replaced by the G glycoprotein of vesicular stomatitis virus, and the use of these vectors in the transfer of exogenous genes into the cells of a wide variety of non-mammalian organisms. Also disclosed is a method for the generation of retroviral vectors in high titers, wherein a recombinant, stable host cell line is provided which harbors the retroviral vector of interest without envelope protein. High-titer retroviral vector production is initiated by introducing nucleic acid encoding a functional membrane-associated protein into the cell line. The vectors disclosed in the present application can be concentrated by ultracentrifugation to titers greater than 109 cfu/ml which are especially useful in human gene therapy trials, and can also infect cells, such as hamster and fish cells, that are ordinarily resistant to infection with vectors containing the retroviral envelope protein.

Abstract: The method of forming a seamed metal tube having a metal coating of this invention includes galvanizing the strip prior to welding. The strip is then formed into an open seam tube and welded in an inert atmosphere with the seam located in the lower portion of the tube. Finally, the metal coating is caused to flow downwardly over the seam, coating the seam by several means. In one embodiment, the strip is preformed into an arcuate shape and galvanized, wherein the zinc coating increases in thickness toward the lateral strip edges, such that the coating will flow over the seam following welding. The tube may also be reheated following welding, preferably in an enclosure containing an inert atmosphere which includes the weld apparatus. In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube, adjacent the seam, driving the molten metal downwardly over the seam to coat the seam. In another embodiment, the lateral edges of the strip are formed with indentions or grooves directed toward the lateral edges which direct the molten metal downwardly over the seam.
