Generation and identification of recombinant CHv with deletion of gC/gE genes. (A) Predicted and actual RFLP analysis of CHv and CHv-ΔgC/gE infectious clones. The obtained DNA was digested with BamH1 and electrophoresed in a 0.7% agarose gel. (line 1:BAC-CHv, line 2: BAC-CHv-ΔgC/gE) (B) Transfection of the plasmids CHv-ΔgC/gE -GS1783 into DEFs resulted in numerous fluorescent spots and cytopathies, the mutant virus CHv-ΔgC/gE were rescued. (C) PCR analysis of the gE expression of CHv-ΔgC/gE. (line 1: CHv-ΔgC/gE, line 2: Mock) (D) DEFs were infected (MOI = 0.01) with CHv-ΔgC/gE or CHv. At 24 h post infection (hpi), the levels of gC and gE proteins were determined with western blotting. (E) DEFs were infected (MOI = 0.1) with CHv-ΔgC/gE, CHv. Expression of gE and gI proteins was detected by indirect immunofluorescence at 36 hpi.
