Hi Jens Rainer. 

I just can say that I tried Alamr Blue, too in order to measure the 
influence of drugs on cell growth. With 3H-thymidin, there was a 
clear signal, but Alamar Blue: No difference. 

Maybe Alamar Blue is just good for making strong effects visible.
Did you make MTT or XTT assays? Did these work? with your cells?
