Figure 3. Comparison for the infectivities of four corresponding replication-defective adenovirus (P9/RFP, P9-4C/RFP, GP/RFP and Ad/RFP) in BJ cells, GPFs and gastric CAFs at 48 h after infection (MOI = 100).
(A) The RFP expression by fluorescent images. (B) The expression of E4orf3 protein (11KDa) by western blotting.
