Sensitivity studies to measure viral attachment with RT-PCR. A) Decreasing amount of virus, MOI 0.05-0.05 × 10-4 TCID50/cell, was incubatedwith 2.5 × 105 cells and bound virus was analysed with RT-PCR. B) Decreasing number of CHO and HeLa cells, 2.5 × 105-2.5 × 102, were incubated with MOI 0.05 TCID50/cell of CVB5 and attached virus was measured with RT-PCR. Results are presented as mean ± SEM.
