Expression of the viral TK polypeptides in Vero cells infected with HSV-1_hBVTK, HSV-1_mBVTK, HSV-1_HSV-1TK, HSV-1_WT, and mock at a multiplicity of infection of 3 PFU, as assessed with Western blot analysis. The antibody raised against viral TK is shown on the right. Vero cells were infected with the indicated HSV-1 recombinants or mock. Gray and black arrows denote BVTK and HSV-1TK protein, respectively.
