Prolonged loading duration fails to improve oncolytic efficacy in the presence of anti-serum. Jurkat cells (A) and BOECs (B) were infected with MV-Edm-GFP at a MOI of 2 for 4 or 24 h. These carrier cells were then mixed with A549 cells at a ratio of 1:1 and co-cultured for 72 h in the absence or presence of anti-serum. The viability of the A549 cells was tested by MTT assay. A549 cells mixed with uninfected carrier cells were used as controls. Results are presented as means ± SDs. Similar results were obtained in two independent experiments; ^#P > 0.05, *P < 0.05, **P < 0.01.
