Abstract:
A herpes simplex virus type 1 (HSV-1) insertion vector, pGal8, was designed for analysis of herpesvirus promoters during virus infection. This vector contains a multiple cloning site (MCS) positioned at the 5' end of the lacZ gene for the insertion of promoter sequences. The MCS and lacZ are flanked by sequences from the HSV-1 thymidine kinase encoding gene (tk) to direct homologous recombination into the tk locus of the viral genome. The utility of this vector is demonstrated by construction and comparison of recombinant viruses that express lacZ from the promoters of the genes encoding glycoprotein C, glycoprotein H and glycoprotein E.
