abstract: This study correlates the fluorescent signal from stable recombinant CHO cell lines expressing the green fluorescent protein (GFP) at high levels with biomass or cell number, extending the use of fluorescent proteins to applications and assays where cell growth rates are important. Using a standard fluorometer, growth of these cells can be quantified noninvasively in multiwell plates, and because signals are obtained without preparation, the same culture samples can be measured repeatedly.
