Figure Lengend Snippet: (A) A549 cells were infected with GRAd32 or GRAd25 at MOI 50 in the presence (w) or absence (w/o) of an anti-CD46 blocking antibody. Images were acquired 3 days post-infection. Competition with CD46 resulted in a delayed onset of cytopathic effect (CPE) exclusively in GRAd25-infected cells. (B) Flow cytometry analysis of surface CAR and CD46 expression levels in lung cancer (A549, NCI-H727, NCI-H1975, NCI-H1299) and normal (MRC5, HUVEC) cell lines. (C) Infection of MRC5 and A549 cells with a replication-defective GRAd32 GFP reporter virus. GFP expression was evaluated at 48 hours post-infection. The presence of GFP signal confirms that GRAd32 is capable of entering MRC5 cells despite its inability to replicate in this cell line.
Article Snippet: For the evaluation of CD46 and CAR cell surface levels, 2-3 x 10 5 cells (MRC5, HUVEC, A549, NCI-H1299, NCI-H1975, NCI-H727) were collected and incubated with anti-human CD46 (1:50; mouse monoclonal; #12239-MM05, Sino Biological) or with anti-human CAR (1:50; rabbit monoclonal; #10799-R271, Sino Biological) for 30 min at 4°C.
