In vitro bioluminescence calculation of MDA-MB-231. a Luciferase-expressing MDA-MB-231 cells were serially diluted in wells from 10,240 to 5 cells/well. Luciferin was added to each well and the plate was imaged with radiance flux (photons/s/cm2/sr). The range of bioluminescence was collected from three experiments. b Total radiance flux from each well was compared to their cell number per well. The correlation between mean radiance flux and injected cell numbers are indicated as R2 values. The error bars represent three independent assays
