Embodiment 1I
[0066] Example 1 Construction method of herpes simplex virus type I infectious clone H129-BAC
[0067] 1. Using the wild-type H129 viral genome as a template, amplify its homologous recombination arm sequence and clone it into a BAC vector containing the GFP gene to obtain a plasmid containing both the H129 homologous recombination arm sequence and the BAC sequence.
[0068] (1) Extraction of wild-type H129 virus genome
[0069] Use the wild-type H129-WT virus (Szpara, M.L.Parsons, L.Enquist, L.W.Sequencevariabilityinclinicalandlaboratoryisolatesofherpessimplexvirus1revealsnewmutations.[J].JVirol.84:5303-13) to infect vero cells at a multiplicity of infection of 1. After infection for 12h, scrape Remove the cells, collect the cell pellet by centrifugation, wash it once with solutionI (10MmTris, 10MmEDTA, pH8.0), and then use 0.5ml of solutionI solution (containing 0.25mgofproteinaseK / ml, purchased from Roche, USA; the final concentration is 0.6% Sodium dodecyl sulfate, purchase...
