Expression of the GFP transgene by d109 in different cell types^a

Cell type	% of cells that were fluorescent inb:
	d109	d106
U2OS	99	96
293	52	80
HeLa	21	89
COS-7	16	90
HCT-116	7	79

WS1 (normal skin fibroblasts)	2	85
MCF7	2	28
HEL (normal embryonic lung fibroblasts)	<1	90

^aCells were infected with the indicated virus at an MOI of 10. At 16 to 18 h postinfection, they were fixed with 3% paraformaldehyde and analyzed for GFP expression on a FACStar flow cytometer.
