Fig. 3From: Safety and immunogenicity of an attenuated Chinese pseudorabies variant by dual deletion of TK&gE genesPlaques of TK&gE dual deletion mutant virus. Plaques are shown under UV excitation(left) or phase control(right). Arrow shows the plaque of rescued virus from BAC PRV△TK/gE/gI. Arrowhead shows the plaque of TK&gE dual deletion mutant virus (PRVΔTK&gE-AH02) after replacement of mini-F sequences through another homologous recombination. Individual panels present views of 600 × 600 μmBack to article page
