Bioluminescence intensities of 66c14 luc- and 4 T1.2 luc-expressing cell lines in vitro . Image analysis show bioluminescence from clonal populations of (A) 66c14 luc(1–5) cells and (B) 4 T1.2 luc(1–5) cells. Green bars highlight 4 T1.2 luc3 and 66c14 luc2 clones with high mean bioluminescence values. Data is expressed as photons/sec/cell (mean ± std dev, n = 4 ) calculated by comparing each cell line to known values of HeLa-Luc cells (350 photons/sec/cell; see Materials and Methods).
