Microscopy of or first fixed cells transfected with various constructs at the Nikon imaging center
Cells tensfected with cmv-GFP, jet-GFP, cmv-jet-GFP
The figure below shows HeLa cells transfected with GFP under a cmv promoter. The image was taken using the Nikon Eclipse 90i upright automated widefield microscope with 40X magnification:

Microscopy of cells transfected with cmv, jet, cmv-jet with GFP and an mCherry control (1:2 ratio)
Measurement of exposure time versus average grey value to check whether there is a linear correlation between the two. This measurement was performed using a fluorescent slide that has constant fluorescence and doesn't bleech. The correlation factor was calculated to be 0.99999. Therefore we can calculate the grey values of samples with different exposure times.
