Herpes simplex virus strains deficient for the essential immediate early genes ICP4 and ICP27 and methods for their production, growth and use
Herpes simplex virus strains deficient for the essential immediate early genes ICP4 and ICP27 and methods for their production, growth and use
Novel cell lines that express complementing levels of herpes simplex virus (HSV) essential immediate early proteins ICP4 and ICP27 and a method of producing the novel cell lines. These novel cell lines are utilized to provide novel HSV strains deficient for both ICP4 and ICP27, and their generation, and novel HSV strains deficient for ICP4 and ICP27 and one or more additional genes, and their generation. Vectors are provided from these methods of using these vectors for gene transfer and for producing site-specific homologous recombinations with cellular DNA.
