Infectivities of pseudotype viruses on CHO cells expressing canine, bovine, or human SLAM. The indicated CHO cell clones were infected with VSVΔG*-G, VSVΔG*-OPHF, VSVΔG*-HA7HF, VSVΔG*-EdHF, VSVΔG*-KAHF, or VSVΔG* (A) or with VSVΔG*-G or VSVΔG*-KOHF (B), and infectious titers were measured by counting the number of GFP-expressing cells.
