CPV infection of human tumor cell lines

	Mock 1	Mock 2	wt CPV 1	wt CPV 2
HepG2	0.17	0.41	4.89	5.06
HeLa	0.54	0.39	9.92	11.4

Notes: Mock- (24 hours post-infection) and CPV-infected (24 hours post-infection) cells were immunolabeled with monoclonal anti-NS1, detected by anti-mouse Alexa 488 antibodies and analyzed with flow cytometer. Flow cytometry scatter diagrams of HepG2 and HeLa cells were used to gate 10,000 cells and the FL1 channel used to obtain the level of NS1 expression. Numbers represent percentage of cells displaying NS1 expression.
