Additional File 2:

Replication of M24-BAC and bM24-BAC in E5 cells. (a) Replication assay of recombinant viruses. 3.8 × 105 E5 cells grown in 12-well plates were infected with the indicated viruses at an MOI of 0.02, viruses were harvested at the indicated times and titered on E5 cells. (b) Virus yield of indicated viruses 74 hours after infection of E5 cells at an MOI of 0.02, from the same experiment as in a. (Error bars show standard deviation. N = 3)
